Photometric moments
WebSep 1, 2024 · The motion of a robot is controlled using a technique called visual servoing that uses feedback information extracted from a vision sensor. In this study, a visual servoing method was proposed based on learning features and image moments for 3D targets to solve the problem of image moments-based visual servoing. WebNov 14, 2024 · Photometric moments are global descriptors of an image that can be used to recover motion information. This paper uses spherical photometric moments for a closed form estimation of 3D rotations from images.

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. WebJan 5, 2024 · The mean is the first statistical moment, but there are three other statistical moments (variance, skew and kurtosis) that are currently not produced globally. In this study, we generated VIIRS day/night band multiyear and annual statistical moments for a widely dispersed set of test areas.
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 …
WebIn this paper, a new method to estimate rotational motions using photometric moments has been provided. The obtained theoretical results have been validated using simulations … Webbacks of photometric visual servoing are the strong non-linearities in the system dynamics: to address this problem, the use of photometric moments has been introduced. Moments capture the characteristics of an unknown distri-bution. They have been applied to image intensity in order to obtain a large convergence domain5 and extended
