Left Ventricle Volume Measurement on Short Axis MRI Images Using a Combined R...IDES Editor
Segmentation and volume measurement of the
cardiac ventricles is an important issue in cardiac disease
diagnosis and function assessment. Cardiac Magnetic
Resonance Imaging (CMRI) is the current reference standard
for the assessment of both left and right ventricular volumes
and mass. Several methods have been proposed for
segmentation and measurement of cardiac volumes like
deformable models, active appearance, shape models, atlas
based methods, etc. In this paper a novel method is proposed
based on a parametric superellipse model fitting for
segmentation and measurement volume of the left ventricle
on cardiac Cine MRI images. Superellipses can be used to
represent in a large variety of shapes. For fitting superellipse
on MR images, a set of data points have been needed as a
partial data. This data points resulted from a semi-automatic
region growing method that segment the homogenous region
of the left ventricle. Because of ellipsoid shape of left ventricle,
fitting superellipse on cardiac cine MRI images has excellent
accuracy. The results show better fitting and also less
computation and time consuming compared to active contour
methods, which is commonly used method for left ventricle
segmentation.
3D Reconstruction of Embryo Hearts for Model ValidationTariq Abdulla
This document describes a method for three-dimensional reconstruction and quantification of human embryonic hearts less than 13 weeks of gestation from histological sections. A human embryo heart of 11 weeks gestation was sectioned, digitized, and matched between sections to create a 3D volume reconstruction. Measurements of internal volumes were obtained. This new approach allows improved visualization and morphological analysis of early embryonic hearts compared to traditional 2D analysis and represents a step towards virtual modeling of cardiac development.
Efficient vessel feature detection for endoscopic image analysisI3E Technologies
The document proposes two new methods for detecting blood vessel features in endoscopic images to serve as distinctive image features for computer-assisted minimally invasive surgery. The methods extract branching points and branching segments of blood vessels. Experimental results show that blood vessel features produce a large number of points that are more robust and repeatable than other types of feature points typically used. Combining vessel features with other general features provides new tools for minimally invasive surgery image analysis. The methods and code are made publicly available.
This document presents a method for automatically identifying and classifying retinal blood vessels in fundus images. The method first segments the vasculature and extracts vessel segments. It then models the segments as a graph and uses Dijkstra's algorithm to identify individual vessel trees based on segment attributes. The method can detect crossings and bifurcations to correctly separate overlapping vessels. It further classifies vessel trees as arteries and veins using features like intensity and a rule that two crossing vessels must have different classifications. The method achieved an average pixel-level classification accuracy of 91.44% on test images. The automated classification allows diagnostically useful analysis of individual retinal vessel morphology.
Comparison of Morphological, Averaging & Median FilterIJMER
The document compares morphological, averaging, and median filters. It begins by introducing morphological filtering theory and the morphological open-closing and close-opening filters. It then discusses generalized open-closing and close-opening filters which aim to overcome limitations of other filters. Spatial domain filtering is explained as operating directly on pixel values. The document concludes by comparing the results of morphological, median, and averaging filters on images with Gaussian noise, finding that the morphological filter performs better with lower error.

Deep segmentation of the liver and the hepatic tumors from abdomen tomography...IJECEIAES
A pipelined framework is proposed for accurate, automated, simultaneous segmentation of the liver as well as the hepatic tumors from computed tomography (CT) images. The introduced framework composed of three pipelined levels. First, two different transfers deep convolutional neural networks (CNN) are applied to get high-level compact features of CT images. Second, a pixel-wise classifier is used to obtain two outputclassified maps for each CNN model. Finally, a fusion neural network (FNN) is used to integrate the two maps. Experimentations performed on the MICCAI’2017 database of the liver tumor segmentation (LITS) challenge, result in a dice similarity coefficient (DSC) of 93.5% for the segmentation of the liver and of 74.40% for the segmentation of the lesion, using a 5-fold cross-validation scheme. Comparative results with the state-of-the-art techniques on the same data show the competing performance of the proposed framework for simultaneous liver and tumor segmentation.

Ensemble Classifications of Wavelets based GLCM Texture Feature from MR Human...rahulmonikasharma
This paper presents an automatic image analysis of multi-model views of MR brain using ensemble classifications of wavelets based texture feature. Primarily, an input MR image has pre-processed for an enhancement process. Then, the pre-processed image is decomposed into different frequency sub-band image using 2D stationary and discrete wavelet transform. The GLCM texture feature information is extracted from the above low-frequency sub band image of 2D discrete and stationary wavelet transform. The extracted texture features are given as an input to ensemble classifiers of Gentle Boost and Bagged Tree classifiers to recognize the appropriate image samples. Image abnormality has extracted from the recognized abnormal image samples of classifiers using multi-level Otsu thresholding. Finally, the performance of two ensemble classifiers performance has analyzed using sensitivity, specificity, accuracy, and MCC measures of two different wavelet based GLCM texture features. The resultant proposed feature extraction technique achieves the maximum level of accuracy is 90.70% with the fraction of 0.78 MCC value.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Blood vessel segmentation of fundus images by major vessel extraction and subimage classification
1. BLOOD VESSEL SEGMENTATION OF FUNDUS IMAGES BY MAJOR VESSEL
EXTRACTION AND SUBIMAGE CLASSIFICATION
ABSTRACT
This paper presents a novel three-stage blood vesselsegmentation algorithm using funds
photographs. In the firststage, the green plane of a fundus image is preprocessed to extracta
binary image after high-pass filtering, and another binary imagefrom the morphologically
reconstructed enhanced image forthe vessel regions. Next, the regions common to both the
binaryimages are extracted as the major vessels. In the second stage, allremaining pixels in the
two binary images are classified using aGaussian mixture model (GMM) classifier using a set of
eight featuresthat are extracted based on pixel neighborhood and first andsecond-order gradient
images. In the third postprocessing stage,the major portions of the blood vessels are combined
with the classifiedvessel pixels. The proposed algorithm is less dependent ontraining data,
requires less segmentation time and achieves consistentvessel segmentation accuracy on normal
images as well asimages with pathology when compared to existing supervised
segmentationmethods. The proposed algorithm achieves a vessel segmentationaccuracy of
95.2%, 95.15%, and 95.3% in an average of3.1, 6.7, and 11.7 s on three public datasets DRIVE,
STARE, andCHASE_DB1, respectively.
