    Class-Dependent Weighted Feature Selection as a Bi-Level Optimization Problem

    Feature selection aims at selecting relevant features from the original feature set, but these features do not have the same degree of importance. This can be achieved by feature weighting, which is a method f...

    Image Segmentation Using Dynamic Run-Length Coding Technique

    In this study, a new segmentation algorithm based on a modified Dynamic Window-based gray-level Run-Length Coding (DW-RLC) applied to neighboring pixels is proposed. The method is applied to gray scale images,...
