Problems solved by technology

However, there are limitations in data expansion. It only expands the scale of the data set and does not improve the quality of target detection information, which will make the feature representation learned by the target detection network not robust enough.
In infrared small sample target detection, this limitation will have a greater impact

Description

technical field [0001] The invention belongs to the field of image processing and relates to an infrared small sample target detection method. Background technique [0002] The human visual system can only receive spectral information of visible light. Experts and scholars have proposed many advanced computer vision target detection methods in the field of visible light images. However, visible light images are easily affected by environmental factors such as weather and light intensity, and it is difficult to perform target detection tasks in certain environments. Infrared images represent the energy or temperature information of the detection target in the current scene by receiving thermal imaging of the target and background radiation, and the information is rarely affected by environmental factors. Therefore, infrared image target detection has become an important research direction. [0003] With the development of deep learning technology, infrared image target dete...
