Photometric moments
WebThis letter proposes to consider the Discrete Cosine Transform (DCT) which allows to represent the image in the frequency domain in terms of a sum of cosine functions that oscillate at various frequencies and uses these coefficients as the visual features that are considered in a visual servoing control law. In this letter, we propose an original approach …

WebPhotometric Moments as visual features We propose a new type of visual features for visual servoing : photometric moments. These global features do not require any segmentation, matching or tracking steps. The analytical form of the interaction matrix is developed in closed form for these features. WebApr 1, 2004 · A model of the photometric transformations describes the way in which the intensities in the red, green, and blue bands ( R, G, B) transform between images. These changes are influenced by the scene illumination, the reflective characteristics of the objects, and the camera sensors.
