This research work is related to the application of machine vision technique to develop a robust assistive human computer interaction technology for those with physical accessibility problem of controlling mouse and keyboard with hand. Paper's main motif is inferring information about planer movement of the head using a video camera and transforming this motion to the pixel coordinate system of the...
Face recognition and expression analysis is one of the most challenging research areas in the field of computer vision. Even though face exhibits different facial expressions, which can be instantly recognized by human eyes, it is very difficult for a computer to extract and use the information content from these expressions. In this paper we present a method to analyze facial expression by focusing...
Pattern recognition problem rely on the features inherent in the pattern of images. Face detection and recognition is one of the challenging research areas in the field of computer vision. In this paper, we present a method to identify skin pixels from still and video images using skin color. Face regions are identified from this skin pixel region. Facial features such as eyes, nose and mouth are...
