Abstract

The invention discloses a sleep abnormity determining method for a low-resolution infrared image. The method belongs to the technical field of artificial intelligence. The method comprises the steps of determining expression of an abnormity of a sleep image in a low-resolution passive far-infrared condition by means of the artificial intelligence, firstly performing targeted preprocessing and characteristic generation on a low-resolution passive far-infrared image of which the kind is marked, training a classifying system, obtaining an appropriate characteristic selecting and extracting method and a classifier method; performing targeted preprocessing and characteristic generation on the low-resolution passive far-infrared image to be determined intelligently, performing classification by means of the selected characteristic selecting and extracting method and the trained classifying system, and obtaining the abnormity output of the low-resolution passive far-infrared image to be determined intelligently. The sleep abnormity determining method for the low-resolution infrared image has advantages of relatively high robustness and relatively low operation complexity in determining the sleep abnormity of the low-resolution passive far-infrared images of different sleep individuals on the condition that a false alarm rate is ensured.

Description

technical field [0001] The invention relates to the technical fields of image processing and artificial intelligence, in particular to a method for judging abnormal sleep conditions of low-resolution infrared images. Background technique [0002] At present, with the increasing development and maturity of image processing and acquisition technology, a large number of applications of artificial intelligence in image processing have emerged in people's daily life. Passive far infrared has the characteristics of clear imaging in the dark, zero radiation, non-contact, and good privacy, and has been widely used. However, due to the high cost of far infrared collection technology, the resolution of low-cost collection equipment for ordinary households is very low. How to use low-resolution passive far-infrared images to judge intelligent abnormal situations is of great significance. On the one hand, this technology can be used to form high-cost-effective, clear imaging in the dar...
