In this paper, a unique biologically inspired retina circuit architecture providing Laplacian filter based analog image processing has been suggested. A digital image filtering method is utilized for this aim. Convolution theory and masking technique have an important place among digital image processing ...
Based on the research progress in the vision and cognition field of psychophysics, neurophysiology and cognitive neuroscience, combined with the methods proposed in the image enhancement in digital image processing field, this paper brings forward a self-adapting median filtering method under muti-window...
Unlike low-pass FIR filters, the median filter tends to preserve the edges in an image. Because of this, median filtering is very widely used in digital image processing. Sign in to download full-size image Figure 4.1. Examples of median filter patterns. View chapter Book 2013, Digital ...

Digital image blind forensics technology is a hot research direction in the field of information security. It can realize the authenticity and integrity verification of digital images without embedding the authentication information in the image in advan
Originally the term filtering was adopted in electrical engineering to refer to that aspect of signal processing which is concerned with the removal from signal of unwanted components such as noise. Until the advent of digital technology, especially of digital computers, filtering was performed exclusiv...
Computer aided diagnosis (CAD) has been proposed as a "second-opinion" strategy for breast screening. This paper presents a new mammographic image processing method using anisotropic diffusion filtering to improve feature enhancement and lesion detection of CAD in digital mammography...
