چکیده
In this research, characterization of Discrete Cosine Transform (DCT) based Gradient Vector Flow (GVF) Active Contours as an efficient boundary mapping technique for chromosome spread images is done. Statistical testing validates the experimental results of characterization. Investigations on a different dataset are carried out to validate the characterized parameters and the parameters are standardized. Further experiments are carried out to evaluate the validity of the standardization using another dataset. Error Quantification justified the successful standardization. It is hence established that DCT based GVF Active Contour is an efficient tool for boundary mapping of chromosome spread images.

متن کاملAccurate Fruits Fault Detection in Agricultural Goods using an Efficient Algorithm
The main purpose of this paper was to introduce an efficient algorithm for fault identification in fruits images. First, input image was de-noised using the combination of Block Matching and 3D filtering (BM3D) and Principle Component Analysis (PCA) model. Afterward, in order to reduce the size of images and increase the execution speed, refined Discrete Cosine Transform (DCT) algorithm was uti...
متن کاملHuman Skin Cancer Recognition and Classification by Unified Skin Texture and Color Features
In this paper we have proposed a novel method called automatic segmentation of skin lesion in conventional macroscopic images. Many approaches have been proposed to determine the skin cancer. An extensive literature survey is done to study the state-of-art techniques for skin cancer recognition; level set active contours (LSAC), skin lesion segmentation (SLS) and multidirectional gradient vecto...
متن کاملExtraction of the Optic Disk Boundary in Digital Fundus Images
The methods of active contours (“snakes”) and level sets were applied to images of the retina in order to locate the outer boundary of the optic disk. A gradient-vector-flow based active contour was used as it performed well over a large range of initial conditions. Images were pre-processed to lessen the influence of blood vessels on boundary detection. Both active contours and level set metho...
متن کاملMultimodal medical image fusion based on Yager’s intuitionistic fuzzy sets
The objective of image fusion for medical images is to combine multiple images obtained from various sources into a single image suitable for better diagnosis. Most of the state-of-the-art image fusing technique is based on nonfuzzy sets, and the fused image so obtained lags with complementary information. Intuitionistic fuzzy sets (IFS) are determined to be more suitable for civilian, and medi...
