Extract of facial feature points has become an important issue in many applications, such as face recognition, expression recognition, and face detection. A method of facial feature extraction-based and corner detection is presented in this paper. In this method we develop a technique for extracting the facial features from a color image captured by the(More)
Denoising of images is one of the vital topics in image manipulating. Approaches for denoising a chain of images aims to attenuate additive noise to the lowest possible rates by using both spatial and temporal areas. Conversely, extracting the edges of images that affected by the White-Gaussian noise was the major dilemma faced by many researchers. Many of(More)
Medical image fusion is the procedure of combining several images from one or multiple imaging modalities. In spite of numerous attempts in direction of automation ventricle segmentation and tracking in echocardiography, due to low quality images with missing anatomical details or speckle noises and restricted field of view, this problem is a challenging(More)
Different approaches to gray and white matter measurements in magnetic resonance imaging (MRI) have been studied. For clinical use, the estimated values must be reliable and accurate when, unfortunately, many techniques fail on these criteria in an unrestricted clinical environment. A recent method for tissue clusterization in MRI analysis has the advantage(More)
BACKGROUND Computerized tomographic angiography (3D data representing the coronary arteries) and X-ray angiography (2D X-ray image sequences providing information about coronary arteries and their stenosis) are standard and popular assessment tools utilized for medical diagnosis of coronary artery diseases. At present, the results of both modalities are(More)
BACKGROUND The identification and segmentation of inhomogeneous image regions is one of the most challenging issues nowadays. The surface vessels of the human heart are important for the surgeons to locate the region where to perform the surgery and to avoid surgical injuries. In addition, such identification, segmentation, and visualisation helps novice(More)

Coronary arterial tree extraction in angiograms is an essential component of each cardiac image processing system. Once physicians decide to check up coronary arteries from x-ray angiograms, extraction must be done precisely, fast, automatically and including whole arterial tree to help diagnosis or treatment during the cardiac surgical operation. This(More)

This paper presents works involves in developing a three-dimensional lips model to be used in a visual speech synthesis. Even though several works have been done in similar areas, but a systematic approach of identifying and determining the number of vertices used in the lips model for visual speech synthesis were not explained thoroughly. Instead of the(More)
