Description

technical field [0001] The invention belongs to the technical field of image display processing, and in particular relates to an automatic gain control display method for floating-point images. Background technique [0002] In applications such as infrared thermal wave non-destructive testing, it is usually necessary to perform data processing on the original infrared image. In order to improve the processing accuracy, the resulting image is usually a floating-point image, and most display systems only accept images in 8-bit integer data format. Signal input, so the floating-point image data needs to be converted into an 8-bit integer image data format suitable for display. [0003] In the process of converting floating-point images to 8-bit plastic images, the gain bias control method is usually used to realize data format conversion and image enhancement, which has the advantages of strong scene adaptability, less resource occupation, and fast processing speed.

Problems solved by technology

[0004] The key problem of the gain bias control method is the automatic acquisition method of the gain coefficient k. In the shaping format image, the gain coefficient k can be calculated by referring to the histogram, so as to obtain a better display effect, but because the floating-point image cannot directly perform the histogram graph statistics, making automatic gain control difficult
