Iterative vessel segmentation of fundus images
This paper presents a novel unsupervised iterative algorithm for segmenting blood vessels in fundus images. The algorithm first enhances vessel pixels and extracts an initial segmentation using thresholding. It then iteratively identifies new vessel pixels using adaptive thresholding of the residual image, and regions them into the existing segmentation. A novel stopping criterion terminates the iterations when false edges are identified instead of actual vessels. The algorithm achieves 93.2%-95.35% segmentation accuracy on abnormal retinal images from the STARE dataset in an average of 2.45 to 8 seconds per image, depending on the dataset. It is also over 90% accurate for segmenting peripapillary vessels.

This document proposes a new unsupervised algorithm-level fusion scheme (UAFS-HCD) to improve the accuracy of pixel-based change detection in multitemporal SAR flood images. The scheme first uses pixel-based change detection to get a preliminary change mask and estimate parameters for object-based change detection. It then derives an unchanged area mask to eliminate areas without changes, reducing errors. Finally, it obtains a final change mask using object-based change detection. When tested on flood detection, the new scheme was more accurate than traditional pixel-based, object-based, and other hybrid change detection methods.

This document discusses techniques for multidetector computed tomography angiography (MDCTA) of the hepatic, pancreatic, and splenic circulations. Key points include:
- MDCTA allows for acquisition of high spatial and temporal resolution data to delineate both vascular anatomy and parenchymal pathology for preoperative planning.
- Biphasic hepatic protocols include arterial and portal venous phases to detect hypervascular tumors. Pancreatic protocols include a parenchymal phase and portal venous phase.

This document describes a study investigating volume of interest (VOI) cone-beam CT (CBCT) using a dynamic blade collimation system and tube current modulation. The system uses a four blade dynamic collimator that can track an arbitrary VOI defined in treatment planning. Measurements showed VOI CBCT improved contrast-to-noise ratio by a factor of 2.2 compared to full-field CBCT for the same dose. Dose was reduced to 15-80% within the central axis plane and less than 1% out of plane compared to full-field CBCT. Incorporating tube current modulation further increased contrast-to-noise ratio by 1.2, providing a total improvement of 2.6

Unified adaptive framework for contrast enhancement of blood vessels
Information about blood vessel structures influences a lot of diseases in the medical realm. Therefore, for proper localization of blood vessels, its contrast should be enhanced properly. Since the blood vessels from all the medical angio-images have almost similar properties, a unified approach for the contrast enhancement of blood vessel structures is very useful. This paper aims to enhance the contrast of the blood vessels as well as the overall contrast of all the medical angio-images. In the proposed method, initially, the vessel probability map is extracted using hessian eigenanalysis. From the map, vessel edges and textures are derived and summed at every pixel location to frame a unique fractional differential function. The resulting fractional value from the function gives out the most optimal fractional order that can be adjusted to improve the contrast of blood vessels by convolving the image using Grunwald-Letnikov (G-L) fractional differential kernel. The vessel enhanced image is Gaussian fitted and contrast stretched to get overall contrast enhancement. This method of enhancement, when applied to medical angio-images such as the retinal fundus, Computerised Tomography (CT), Coronary Angiography (CA) and Digital Subtraction Angiography (DSA), has shown improved performance validated by the performance metrics.
Optic Disk and Retinal Vesssel Segmentation in Fundus Images
This document presents research on segmenting the optic disk and retinal vessels in fundus images. It describes an algorithm that first applies anisotropic diffusion filtering and thresholding to enhance and extract the retinal vessel network. A graph cut method is then used to segment the optic disk, using either an MRF image reconstruction method or compensation factor method to address overlap of vessels into the optic disk region. The MRF method reconstructs the image in the optic disk region to remove vessels before segmentation, while the compensation factor incorporates local intensity characteristics of vessels. Experimental results on fundus images demonstrate the algorithm can accurately segment the optic disk and retinal vessels.

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.

ABSTRACT
Measurements of retinal blood vessel morphology have been shown to be related to the risk of cardiovascular diseases. The wrong identification of vessels may result in a large variation of these measurements, leading to a wrong clinical diagnosis. In this paper, we address the problem of automatically identifying true vessels as a post processing step to vascular structure segmentation. We model the segmented vascular structure as a vessel segment graph and formulate the problem of identifying vessels as one of finding the optimal forest in the graph given a set of constraints. We design a method to solve this optimization problem and evaluate it on a large real-world dataset of 2,446 retinal images. Experiment results are analyzed with respect to actual measurements of vessel morphology. The results show that the proposed approach is able to achieve 98.9% pixel precision and 98.7% recall of the true vessels for clean segmented retinal images, and remains robust even when the segmented image is noisy.

Automated feature extraction for early detection of diabetic retinopathy i
This document describes an automated method for detecting features in retinal images that can help diagnose diabetic retinopathy. It first extracts blood vessels at multiple scales using morphological operations. It then detects exudates by finding bright regions with sharp edges using dilation across scales. The optic disk is localized by finding the intersection of major blood vessels. Microaneurysms and hemorrhages are detected using morphological filters exploiting their local dark patch property. Evaluation on 516 images achieved 97.1% optic disk localization, 95.7% sensitivity and 94.2% specificity for exudate detection, and 95.1% sensitivity and 90.5% specificity for microaneurysm/hemorrhage detection.

- An investigation was conducted of kV CBCT image quality and dose reduction for volume-of-interest (VOI) imaging using dynamic collimation.
- A prototype iris aperture was used to dynamically collimate the radiation field as a function of gantry angle to track a predefined VOI, reducing scatter and improving image quality while lowering dose outside the VOI.
- Preliminary results found that VOI imaging reduced scatter ratios by up to a factor of 8.4 compared to full-field imaging, lowered dose outside the VOI by up to 90%, and improved contrast-to-noise ratio by a factor of 2, demonstrating the potential for improved image guidance with reduced patient dose.
IRJET- Retinal Blood Vessel Tree Segmentation using Fast Marching Method
1) The document describes a study that used the Fast Marching Method (FMM) to segment retinal blood vessels from fundus images.
2) The FMM algorithm was validated using two public datasets, DRIVE and STARE, achieving segmentation accuracy of 93% on DRIVE images within 5-10 minutes and 90% accuracy on STARE images within 15 minutes.
3) By comparing FMM to other techniques like matched filters, the results showed FMM performance was close to higher resolution methods and overcame some other techniques.

1) The document describes a study that used the Fast Marching Method (FMM) to segment retinal blood vessels from fundus images.
2) The FMM algorithm was validated using two public datasets, DRIVE and STARE, achieving segmentation accuracy of 93% on DRIVE images within 5-10 minutes and 90% accuracy on STARE images within 15 minutes.
3) By comparing FMM to other techniques like matched filters, the results showed FMM performance was close to higher resolution methods and overcame some other techniques.

Iterative vessel segmentation of fundus images
- 1. ITERATIVE VESSEL SEGMENTATION OF FUNDUS IMAGES ABSTRACT This paper presents a novel unsupervised iterative blood vessel segmentation algorithm using fundus images. First, a vessel enhanced image is generated by to phat reconstruction of the negative green plane image. An initial estimate of the segmented vasculature is extracted by global thresholding the vessel enhanced image. Next, new vessel pixels are identified iteratively by adaptive thre sholding of the residual image generated by masking out the existing segmented vessel estimate from the vessel enhanced image. The new vessel pixels are, then, region grown into the existing vessel, thereby resulting in an iterative enhancement of the segmented vessel structure. As the iterations progress, the number of false edge pixels identified as new vessel pixels increases compared to the number of actual vessel pixels. A key contribution of this paper is a novel stopping criterion that terminates the iterative process leading to higher vessel segmentation accuracy. This iterative algorithm is robust to the rate of new vessel pixel addition since it achieves 93.2–95.35% vessel segmentation accuracy with 0.9577–0.9638 area under ROC curve (AUC) on abnormal retinal images from the STARE dataset. The proposed algorithm is computationally efficient and consistent in vessel segmentation performance for retinal images with variations due to pathology, uneven illumination, pigmentation, and fields of view since it achieves a vessel segmentation accuracy of about 95% in an average time of 2.45, 3.95, and 8 s on images from three public datasets DRIVE, STARE, and CHASE_DB1, respectively. Additionally, the proposed algorithm has more than 90% segmentation accuracy for segmenting peripapillary blood vessels in the images from the DRIVE and CHASE_DB1 datasets.
