Color Image Segmentation Technique Using “Natural Grouping” of PixelsCSCJournals
This paper focuses on the problem Image Segmentation which aims at sub dividing a given image into its constituent objects. Here an unsupervised method for color image segmentation is proposed where we first perform a Minimum Spanning Tree (MST) based “natural grouping” of the image pixels to find out the clusters of the pixels having RGB values within a certain range present in the image. Then the pixels nearest to the centers of those clusters are found out and marked as the seeds. They are then used for region growing based image segmentation purpose. After that a region merging based segmentation method having a suitable threshold is performed to eliminate the effect of over segmentation that may still persist after the region growing method. This proposed method is unsupervised as it does not require any prior information about the number of regions present in a given image. The experimental results show that the proposed method can find homogeneous regions present in a given image efficiently.
ImageCLEF 2014 is part of the CLEF 2014 to be held in the city of Sheffield in the United Kingdom. It will organize the four main tasks to benchmark the challenging task of image annotation for a wide range of source images and annotation objective, such as general multi-domain images for object or concept detection, as well as domain-specific tasks such as visual-depth images for robot vision and volumetric medical images for automated structured reporting.

Disaster risk reduction and preparedness plan kalmunai (english)Jowsi Abdul Jabbar
The Disaster Risk Reduction and Preparedness Plans for the city identifies disaster risk reduction strategies . The Plan was prepared by conducting a comprehensive analysis of background information which includes baseline assessments, technical studies incorporating findings of vulnerability and risk assessments through stakeholder consultation.
The DRR and Preparedness Plan is an application of the Hyogo Framework for Action (HFA), a tool that focuses on resilient city development. Fundamentals of the Plan and proposed projects are aligned with priorities for action from the HFA to establish the city as role model resilient city in Sri Lanka.

Object extraction from satellite imagery using deep learningAly Abdelkareem
Presentation for extract objects from satellite imagery using deep learning techniques. you find a comparison between state-of-art approaches in computer vision.
https://imatge.upc.edu/web/publications/efficient-exploration-region-hierarchies-semantic-segmentation
The motivation of this work is the efficient exploration of hierarchical partitions for semantic segmentation as a method for locating objects in images. While many efforts have been focused on efficient image search in large-scale databases, few works have addressed the problem of locating and recognizing objects efficiently within a given image. My work considers as an input a hierarchical partition of an image that defines a set of regions as candidate locations to contain an object. This approach will be compared to other state of the art algorithms that extract object candidates for an image. The final goal of this work is to semantically segment images efficiently by exploiting the multiscale information provided by a hierarchical partition, maximizing the accuracy of the segmentation when only a very few regions of the partition are analysed.

MediaEval 2015 - UNED-UV @ Retrieving Diverse Social Images Task - Postermultimediaeval
This paper details the participation of the UNED-UV group at the 2015 Retrieving Diverse Social Images Task. This year, our proposal is based on a multi-modal approach that firstly applies a textual algorithm based on Formal Concept Analysis (FCA) and Hierarchical Agglomerative Clustering (HAC) to detect the latent topics addressed by the images to diversify them according to these topics. Secondly, a Local Logistic Regression model, which uses the low level features and some relevant and non-relevant samples, is adjusted and estimates the relevance probability for all the images in the database.
