Abstract
The article is devoted to the optimization of local image feature detectors. They can be used in mobile augmented reality video information systems. A study was conducted of the effectiveness of using a brightness preliminary detector in conjunction with a Harris angle detector. The simulation results showed a reduction in the duration of detection of local features of the test image (on average 220 times), a reduction in the number of identified image features and a slight change in the threshold value of the angle response.
