Weba constant amount of time. Our algorithm for generating summed-area tables, similar to a technique used in sci-entiﬁc computing called recursive doubling, allows the generation of a summed-area table in O(log n) time. We also describe a technique to mitigate the precision requirements of summed-area tables. The ability to calculate and use ... WebTo ensure real time, high accuracy and reliable fabric defect detection this paper developed a fast and parallel normalized cross-correlation algorithm based on summed-area table technique called PFDD-SAT. To meet real-time requirements, extensive use of the NVIDIA CUDA framework for Graphical Processing Unit (GPU) computing is made.

WebA summed-area table is a data structure and algorithm for quickly and efficiently generating the sum of values in a rectangular subset of a grid. In the image processing domain, it is also known as an integral image.It was introduced to computer graphics in 1984 by Frank Crow for use with mipmaps.In computer vision it was popularized by Lewis and then given the … WebThe first example of this technique, the “mip” map, uses a set of tables containing successively lower-resolution representations filtered down from the discrete texture function. An alternative method using a single table of values representing the integral over the texture function rather than the function itself may yield superior results at similar cost. dr sanjay gupta jreWebSummed area table algorithm has been used to accelerate some computer vision and signal processing algorithms.
