Faces represent complex, multidimensional, meaningful visual stimuli and developing a computational model for face recognition is difficult [1]. In this paper we propose a new approach to detect the human faces quickly and efficiently by using Eigen faces technique along with ANN using resilient back propagation algorithm. In this process the face structure can be converted into Eigen values. T...

An effort has been made to test the potential of principal component analysis (PCA) method for quantifying and classifying the ultrasound kidney images. For our analysis two different classes of kidney images namely normal (NR) and medical renal diseases (MRD) are considered. The eigen values and vectors are derived for a set of 40 images. The weight vectors (WV) are estimated from the obtained...

Sign Language Recognition has emerged as one of the important area of research in Computer Vision. The difficulty faced by the researchers is that the instances of signs vary with both motion and appearance. Thus, in this paper a novel approach for recognizing various alphabets of Indian Sign Language is proposed where continuous video sequences of the signs have been considered. The proposed s...

In this paper the spatial instability of Kuo’s problem has been discussed. Some stability results have been established for 0 > r k . The spectrum of eigen values has been obtained.

In this paper, proposes an efficient method for change detection in forest areas using panchromatic stereo imagery and Multispectral imagery using kernel minimum noise fraction analysis. Due to low spectral information it is difficult to extract the change features, since changes mostly occur together with other unrelated changes such as environmental changes and seasonal changes. Hence the ker...

In this research work, face recognition for the compressed images is evaluated when the images are stored at smaller sizes. When the images are stored at smaller sizes, the information is lost and sometimes it is not possible to recognize the faces successfully. The practical applications and need for storing the images at smaller sizes is explained. The results for successful recognition are p...

A retrospective evaluation of attitudinal, behavioural and knowledge change among diverse stakeholder groups was conducted in Limpopo Province of South Africa to assess the effectiveness of a series of values clarification (VC) interventions. Telephone and face-to-face interview (193) results revealed that over two-thirds (70.2%) reported behavioural changes and 93.2% reported increased compass...
