WebApr 12, 2024 · Checksum is a mathematical algorithm used to verify data accuracy and integrity during transmission in computer networks. It calculates a unique value for each data block, which is sent alongside the data. The receiving system calculates its own checksum and compares it to the sender's. Mismatches indicate errors or damages … WebMar 15, 2024 · The SIFT descriptor generation is based on the computation of the feature descriptor for each keypoint. The feature descriptor consists of 128 orientation histograms. In the figure below, you can see the image gradients, the keypoint descriptors, and the 128 features for one keypoint as a sequence of this operation that is used in SIFT.
