Fast feature detection by reducing an area of a camera image
First Claim
Patent Images
1. A method for defining a search area for a computer vision algorithm, the method comprising:
- displaying an image, captured by a camera, having a first area;
receiving a selection by a user of a portion of the image; and
defining, based on the portion of the image, a search area for a computer vision algorithm;
wherein a search by the computer vision algorithm is limited to an area within the search area; and
wherein the search area is reduced as compared to the first area.

Abstract
An apparatus and method for a mobile device to reduce computer vision (CV) processing, for example, when detecting features and key points, is disclosed. Embodiments herein reduce the search area of an image or the volume of image data that is searched to detect features and key points. Embodiments limit a search area of a full image to an actual area of interest to the user. This reduction decreases the search area, decreases search time, decreases power consumption, and limits detection to the area of interest to the user.
