SIFT (Scale-Invariant Feature Transform) Algorithm What if the image is scaled up? For this, scale-space filtering is used. In it, Laplacian of Gaussian is found for the image with various σ values.

This is a highly optimised implementation of the FAST feature detector. As described in ... Extremely concise version of the algorithm. Points on a circle are compared against the center point, the ...

However, there are some obstacles to implement on low-power devices such as its high computational intensity. This paper presents the feature detection and description algorithm based on ORB algorithm ...

Abstract: In this paper, it is aimed to implement object detection and recognition algorithms for ... is preferred. Local feature-based algorithms such as SIFT, SURF, FAST, and ORB are used on the ...
