The histogram specification turns a shape of a histogram into that we want to specify. This technique can be applied usefully in various image processing fields such as machine vision. However, the histogram specification technique has its basic limits. For instance, the histogram does not have location information of pixels. Also, the accuracy of specification drops because of quantization error...
Liver segmentation on computed tomography (CT) images is a challenging task due to the anatomic complexity and the imaging system noise. In this paper, we develop an improved level set segmentation method. Our region-based level-set approach has many advantages over the conventional active contour models. First, the improved model can get much smoother contour by adding a signed distance preserving...
Transmission of mammographic images in real time and of sufficient accuracy to render accurate diagnosis is under demand. This requires efficient lossless image compression schemes. Image compression has been a major research area for the past few decades despite the massive growth in data storage and transmission speeds. Moreover, wavelets have become the cutting edge techniques in image compression...
