Vergence has transient components that are stimulated by brief presentations of stimuli at large disparities (up to several degrees). The question that we have addressed is what stimulus features are encoded by this system. A competition paradigm [Jones & Kerr, (1972)]. Vision Research, 12, 1425-1430) was used in which three gabors were presented. A single Gabor was presented to the fovea of on...

This article presents a new method of image filtering based on kind processing transformation, particularly the wavelet-Ateb–Gabor that is wider basis for Gabor functions. Ateb functions are symmetric The developed type makes it possible to perform transformation and obtain better biometric recognition results than traditional filters allow. These due construction various forms sizes curves Fur...

This quarter we primarily worked on optimizing the edge and line detectors incorporated in our image analysis software. We changed our optimization scenario and designed a metric for the evaluation procedure. With our optimized detectors, we achieved a match error rate of 29.3%, as well as a low level of insertion, on the test set 01 from the Pre-phase 01 image data. Meanwhile, we started inves...

Gaussian and Gabor patches can be accurately localized; however, it is not yet clear which cues (or location tags) the visual system utilizes for localization. To determine the cues used in spatial alignment, we measured and modelled the perceived shifts for asymmetric Gaussian and Gabor patches over a wide range of separations, patch sizes and orientations. For Gaussian patches we observed per...

Biometric authentication using fingerprint is one of the unique and reliable method of verification processes. Biometric System suffers a signiûcant loss of performance when the sensor is changed during enrollment and authentication process. In this paper fingerprint sensor interoperability problem is addressed using Gabor ûlter and classifying images into good and poor quality. Gabor ûlters pl...

Facial Expression Recognition has been a very important topic for research in computer pattern recognition and currently there is no method of facial Expression recognition system that have 100% recognition rate. The purpose of this research paper is to analysis of performance of Gabor filter and average Gabor filter. Feature extraction is the key step on which recognition rate depends for faci...

Multi-view face detection in open environments is a challenging task, due to the wide variations in illumination, face appearances and occlusion. In this paper, a robust method for multi-view face detection in open environments, using a combination of Gabor features and neural networks, is presented. Firstly, the effect of changing the Gabor filter parameters (orientation, frequency, standard d...
