Ischemic stroke is the most commonly occurring type of stroke and the most communal cause for disability and death in the world. Apart from clinical tests, a lot of research is conducted on computer based automated techniques for ischemic stroke risk estimation. Ultrasound images of the carotid artery are used in noninvasive image based methods for stroke risk estimation. Carotid artery morphology, noise and artifacts in the ultrasound images can lead to false classification. In this book, we have proposed an automatic ischemic stroke risk estimation approach using carotid intima media...

The recognition of handwritten characters is a vital research area in the domain of text segmentation. Various approaches have evolved in the past and intensive research is still being carried out, at present. In this book, we have presented a geometrical feature based approach to recognize handwritten characters. The strength of the approach is in the comprehensive classification scheme due to which, we have been able to achieve a recognition rate of 95.8%, better than the previous approaches.The book may be very helpful for researchers and academicians working in the domain of handwritten...

Recognition of hand gestures associated with different alphabets is a very important research area. The persons with vocal and hearing disabilities will benefit a lot from this research. The communication gap between these and normal persons is filled by providing an aid in the form of a computerized translation of different hand gestures. In this research, a recognition system is being developed to translate hand gestures into Urdu alphabets. A comprehensive classification scheme has been formulated which is core to this recognition system. The accuracy rate of proposed approach is 97.4%...
