This document provides an overview of a CVPR 2010 tutorial on semi-supervised learning in vision. The tutorial covered semi-supervised learning theory and methods, including self-training, generative models, margin assumptions, and multi-view learning. It also discussed applications of semi-supervised learning to tasks like object detection, categorization, tracking, and activity recognition. Finally, the tutorial addressed why techniques like semi-supervised learning, online learning, and dealing with noisy labels are important for vision problems involving large datasets with limited labeled data.
CVPR2010: Semi-supervised Learning in Vision: Part 2: Theoryzukun
The document discusses semi-supervised learning in computer vision. It begins by explaining that semi-supervised learning uses both labeled and unlabeled data to find patterns and make predictions. It notes several common computer vision problems where semi-supervised learning is applicable, including object recognition, detection, tracking and segmentation, because similar images or pixels may contain similar objects or belong to the same object. The document outlines different settings for semi-supervised learning, such as classification, regression and clustering. It also distinguishes between transductive and inductive learning approaches.
CVPR2010: Semi-supervised Learning in Vision: Part 3: Algorithms and Applicat...zukun
The document summarizes research on semi-supervised learning techniques in computer vision, including SemiBoost. SemiBoost is an algorithm that uses a small amount of labeled data and a large amount of unlabeled data to train classifiers. It works by iteratively computing pseudo-labels and weights for unlabeled data based on a similarity measure, then retraining a weak learner. The document discusses extensions of SemiBoost, including learning distance functions from labeled data to define similarities, reusing priors from previous classifiers, and applications to tasks like car detection.
This document discusses the importance of good research data and data curation. It notes that data is valuable and can enable more research, teaching and learning if properly managed and preserved. The document outlines reasons to care about data curation, such as enabling data reuse, accountability and meeting legal requirements. It also discusses challenges that occur without good research data management practices, and the benefits that can arise from proper data curation, such as enabling more impact from research.
Artificial agents interacting in highly dynamic environments are required to continually acquire and fine-tune their knowledge overtime. In contrast to conventional deep neural networks that typically rely on a large batch of annotated training samples, lifelong learning systems must account for situations in which the number of tasks is not known a priori and the data samples become incrementally available over time. Despite recent advances in deep learning, lifelong machine learning has remained a long-standing challenge due to neural networks being prone to catastrophic forgetting, i.e., the learning of new tasks interferes with previously learned ones and leads to abrupt disruptions of performance. Recently proposed deep supervised and reinforcement learning models for addressing catastrophic forgetting suffer from flexibility, robustness, and scalability issues with respect to biological systems. In this tutorial, we will present and discuss well-established and emerging neural network approaches motivated by lifelong learning factors in biological systems such as neurosynaptic plasticity, complementary memory systems, multi-task transfer learning, and intrinsically motivated exploration.

Horst Bischof discusses the history of vision and his own involvement in the field. He started working with neural networks for protein folding and land cover classification. Over time, his work shifted to focus more on statistical pattern recognition methods like subspaces, robustness, and online learning. Conferences like NIPS, CVPR, ICCV, and ECCV have grown substantially in size over the years. Topics that were initially popular at NIPS like neural networks, reinforcement learning, and MDL influenced vision research. Learning approaches are becoming increasingly important for solving large-scale vision problems. Understanding the history provides insights into trends in the field and upcoming research areas.

This document summarizes a presentation on natural image statistics given by Siwei Lyu at the 2009 CIFAR NCAP Summer School. The presentation covered several key topics:
1) It discussed the motivation for studying natural image statistics, which is to understand representations in the visual system and develop computer vision applications like denoising.
2) It reviewed common statistical properties found in natural images like 1/f power spectra and non-Gaussian distributions.
3) Maximum entropy and Bayesian models were presented as approaches to model these statistics, with Gaussian and independent component analysis discussed as specific examples.
4) Efficient coding principles from information theory were introduced as a framework for understanding neural representations that aim to decorrelate and
Camera calibration involves determining the internal camera parameters like focal length, image center, distortion, and scaling factors that affect the imaging process. These parameters are important for applications like 3D reconstruction and robotics that require understanding the relationship between 3D world points and their 2D projections in an image. The document describes estimating internal parameters by taking images of a calibration target with known geometry and solving the equations that relate the 3D target points to their 2D image locations. Homogeneous coordinates and projection matrices are used to represent the calibration transformations mathematically.
Brunelli 2008: template matching techniques in computer visionzukun
The document discusses template matching techniques in computer vision. It begins with an overview that defines template matching and discusses some common computer vision tasks it can be used for, like object detection. It then covers topics like detection as hypothesis testing, training and testing techniques, and provides a bibliography.
The HARVEST Programme evaluates feature detectors and descriptors through indirect and direct benchmarks. Indirect benchmarks measure repeatability and matching scores on the affine covariant testbed to evaluate how features persist across transformations. Direct benchmarks evaluate features on image retrieval tasks using the Oxford 5k dataset to measure real-world performance. VLBenchmarks provides software for easily running these benchmarks and reproducing published results. It allows comparing features and selecting the best for a given application.
This document summarizes VLFeat, an open source computer vision library. It provides concise summaries of VLFeat's features, including SIFT, MSER, and other covariant detectors. It also compares VLFeat's performance to other libraries like OpenCV. The document highlights how VLFeat achieves state-of-the-art results in tasks like feature detection, description and matching while maintaining a simple MATLAB interface.
This document summarizes and compares local image descriptors. It begins with an introduction to modern descriptors like SIFT, SURF and DAISY. It then discusses efficient descriptors such as binary descriptors like BRIEF, ORB and BRISK which use comparisons of intensity value pairs. The document concludes with an overview section.
This document discusses various feature detectors used in computer vision. It begins by describing classic detectors such as the Harris detector and Hessian detector that search scale space to find distinguished locations. It then discusses detecting features at multiple scales using the Laplacian of Gaussian and determinant of Hessian. The document also covers affine covariant detectors such as maximally stable extremal regions and affine shape adaptation. It discusses approaches for speeding up detection using approximations like those in SURF and learning to emulate detectors. Finally, it outlines new developments in feature detection.
The document discusses modern feature detection techniques. It provides an introduction and agenda for a talk on advances in feature detectors and descriptors, including improvements since a 2005 paper. It also discusses software suites and benchmarks for feature detection. Several application domains are described, such as wide baseline matching, panoramic image stitching, 3D reconstruction, image search, location recognition, and object tracking.
System 1 and System 2 were basic early systems for image matching that used color and texture matching. Descriptor-based approaches like SIFT provided more invariance but not perfect invariance. Patch descriptors like SIFT were improved by making them more invariant to lighting changes like color and illumination shifts. The best performance came from combining descriptors with color invariance. Representing images as histograms of visual word occurrences captured patterns in local image patches and allowed measuring similarity between images. Large vocabularies of visual words provided more discriminative power but were costly to compute and store.
This document summarizes a research paper on internet video search. It discusses several key challenges: [1] the large variation in how the same thing can appear in images/videos due to lighting, viewpoint etc., [2] defining what defines different objects, and [3] the huge number of different things that exist. It also notes gaps in narrative understanding, shared concepts between humans and machines, and addressing diverse query contexts. The document advocates developing powerful yet simple visual features that capture uniqueness with invariance to irrelevant changes.
The document discusses computer vision techniques for object detection and localization. It describes methods like selective search that group image regions hierarchically to propose object locations. Large datasets like ImageNet and LabelMe that provide training examples are also discussed. Performance on object detection benchmarks like PASCAL VOC is shown to improve significantly over time. Evaluation standards for concept detection like those used in TRECVID are presented. The document concludes that results are impressively improving each year but that the number of detectable concepts remains limited. It also discusses making feature extraction more efficient using techniques like SURF that take advantage of integral images.
This document provides an outline and overview of Yoshua Bengio's 2012 tutorial on representation learning. The key points covered include:
1) The tutorial will cover motivations for representation learning, algorithms such as probabilistic models and auto-encoders, and analysis and practical issues.
2) Representation learning aims to automatically learn good representations of data rather than relying on handcrafted features. Learning representations can help address challenges like exploiting unlabeled data and the curse of dimensionality.
3) Deep learning algorithms attempt to learn multiple levels of increasingly complex representations, with the goal of developing more abstract, disentangled representations that generalize beyond local patterns in the data.

The tutorial demonstrates features of Gephi including node ranking, partitioning, and interactive visualization of the graph.
EM algorithm and its application in probabilistic latent semantic analysiszukun
The document discusses the EM algorithm and its application in Probabilistic Latent Semantic Analysis (pLSA). It begins by introducing the parameter estimation problem and comparing frequentist and Bayesian approaches. It then describes the EM algorithm, which iteratively computes lower bounds to the log-likelihood function. Finally, it applies the EM algorithm to pLSA by modeling documents and words as arising from a mixture of latent topics.
This document describes an efficient framework for part-based object recognition using pictorial structures. The framework represents objects as graphs of parts with spatial relationships. It finds the optimal configuration of parts through global minimization using distance transforms, allowing fast computation despite modeling complex spatial relationships between parts. This enables soft detection to handle partial occlusion without early decisions about part locations.
Iccv2011 learning spatiotemporal graphs of human activities zukun
The document presents a new approach for learning spatiotemporal graphs of human activities from weakly supervised video data. The approach uses 2D+t tubes as mid-level features to represent activities as segmentation graphs, with nodes describing tubes and edges describing various relations. A probabilistic graph mixture model is used to model activities, and learning estimates the model parameters and permutation matrices using a structural EM algorithm. The learned models allow recognizing and segmenting activities in new videos through robust least squares inference. Evaluation on benchmark datasets demonstrates the ability to learn characteristic parts of activities and recognize them under weak supervision.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Semi-Supervised Learning
SSL is Supervised Learning...
Goal: Estimate P(y|x) from Labeled Data
Dl={ (xi,yi) }
p( x | y ) p( y )
p( y | x) =
P( x)
But: Additional Source tells about P(x)
(e.g., Unlabeled Data Du={xj})
The Interesting Case:

SSL is biologically plausible
• Co-training by infants [Bahrick et.al. 2002]
• Human change model once they see unlabeled data
[Zahki et.al. 2007,Zhu et.al. 2007,Vandist et.al. 2007]
• Humans do On-line SSL [Zhu ICML 2010]

Why?
1. Unlabelled data is cheap/free
2. Labeled data is hard to get
• human annotation is boring
• labels may require experts
• labels may require special devices
• your graduate student is on vacation

Why on-line learning?
Too much training data to fit in memory
– Internet!!!
Sample generation process
– Tracking, Co-Training
Changing processes
– Changing Environment

Why on-line learning?
Specializing
– Forget irrelevant information
– Specialize to current scene
Interactive Applications
– Data labeling
– Classifier Training
– Specializing (Human in the loop)
– Interactive Training (Segmentation)
