The color appearance of an object can vary widely as a function of camera sensitivity and ambient illumination. In this paper, we discuss a methodology for seamless interfacing across imaging sensors and under varying illumination conditions for two very relevant problems in aerial imaging, namely, change detection and mosaicing. The proposed approach works by estimating surface reflectance which...
The deviation from perfect symmetry of the left and right sides of a bilateral animal is known to indicate the developmental stress of the animal. It has also been used to study the general health of a population. For animals like tigers and zebras which have natural stripes on their bodies, the asymmetry between the two sides can be measured by analysing the stripe patterns taken from images of these...
Background modeling and subtraction is a core component of many vision based systems. By far the most popular background models are per-pixel models, in which each pixel is considered independently. Such models fail to handle dynamic backgrounds and noise. In this paper, we present a solution to this problem by proposing a novel and computationally simple spatio-temporal background model. We extend...
AM-FM models analyze an image in terms of amplitude and frequency modulated sinusoids. Such models are well suited to describe the local non-stationarities of an image. In this paper, the invariance of AM-FM features with respect to scaling, rotation and illumination changes is presented. These properties can be used in applications of AM-FM image models where features for affine transformed images...
