Glaucoma is an eye disease that the second leading cause of blindness. Examination glaucoma by ophthalmologist usually done observing retinal image directly. Observations from one doctor to another may differ, depending on their educational background, experience, and psychological condition. Therefore, a detection system based digital processing needed. The or classification with strongly infl...

In this paper the analysis of gray level corner detections has been carried out. The performances of cornerness measures for some corner detection algorithms are discussed. This paper presents a new approach for corner detection called the GradientDirection corner detector which is developed from the popular Plessey corner detector. The GradientDirection corner detector is based on the measure ...

The aim of this paper is image encryption using Genetic Algorithm (GA). The proposed encryption method consists of two phases. In modification phase, pixels locations are altered to reduce correlation among adjacent pixels. Then, pixels values are changed in the diffusion phase to encrypt the input image. Both phases are performed by GA with binary chromosomes. For modification phase, these bin...

This work presents a method for automatic texture segmentation based on k-means clustering technique and cooccurrence texture features. A set of features was extracted from 256 gray-level co-occurrence information. These features were used to segment image regions regarding the textural homogeneity of its areas. As the process of calculating co-occurrence information demands the majority of com...
