Edge detection has beneficial applications in the fields such as machine vision, pattern recognition and biomedical imaging etc. Edge detection highlights high frequency components in the image. Edge detection is a challenging task. It becomes more arduous when it comes to noisy images. This study focuses on fuzzy logic based edge detection in smooth and noisy clinical images. The proposed meth...
Abstract Visual identification of objects is an important challenge today. Main target frequently applied methods to identify or classify complex objects. These are far less effective when small and complex, thus descriptor features on hand. The main reason for this that these can significantly change object occlusion appearance noise. presented solution performs simple, (size 17 × 13 pixels) w...
finger vein is one of the most fitting biometric for identifying individuals. in this paper a new method for finger vein recognition is proposed. first the veins are extracted from finger vein images by using entropy based thresholding. in finger vein images the veins are appeared as dark lines. the method extracts veins as well, but the images are noisy, that means in addition to the veins the...
