dc.description.abstractUnder natural viewing conditions humans tend to fixate on specific parts of the image that interests them naturally. Saliency map is the map of regions which are more prominent than other regions in terms of low level image properties such as intensity, color and orientation. With some modifications it can be used to simulate the natural human fixation also known as the gaze map. There are numerous applications in the field of engineering, marketing and art that can benefit from understanding of human visual fixation such as image quality evaluation, label design etc. The objective of this research is to understand the factors that influence the saliency map and gaze map and to modify the saliency map in order to make it similar to the gaze map. Eye movements of 20 test subjects were captured using eye tracking equipment available in the lab. The gaze maps obtained were averaged and superimposed over the corresponding original images. Saliency map toolbox [Walther(2006)] was modified by addition of face detection [Sauquet et al.(2005)Sauquet, Rodriguez & Marcel]. The gaze maps were analyzed and compared with modified saliency maps.en
