Embodiment Construction
[0048] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0049] see figure 1 , is a process flow of an area image enhancement method based on object detection related to an embodiment of the present invention. The method comprises the steps of:
[0050] First enter step S101 to control the image acquisition unit to acquire the original image. The original image is an image in RGB format. The image acquisition unit may be an electronic component with an image acquisition function, such as a camera; it may also be an electronic device including a camera, such as an industrial camera.
[0051]Then enter step S102 to convert the original image collected by the image acquisition unit from the RGB format to the LAB format, and obtain the L component image. The LAB format is a color mode under...

The invention discloses an area image enhancement method based on object detection and a storage medium. According to the method of the invention, a focused objective area (namely a to-be-enhanced area) in the image is determined according to a saliency characteristic of an object; and through performing local enhancement processing on the focused area, higher clarity of the image information in the to-be-enhanced area can be realized. Compared with a mode of performing global enhancement processing on the whole image, the area image enhancement method provided by the invention has advantagesof effectively improving enhancement processing efficiency, improving the enhancement effect of the focused area, improving observation precision and efficiency, and facilitating browsing and capturing of an observer to the image information of the focused area on the image. Furthermore, according to the area image enhancement method and the storage medium, the related threshold of the algorithm can be changed according to different precision requirements. The area image enhancement method and the storage medium have advantages of high flexibility, extensive applicability, etc.
Description
technical field [0001] The present invention relates to the field of image processing, in particular to an area image enhancement method based on target detection and a storage medium. Background technique [0002] The method of image enhancement is to add some information or transform data to the original image by certain means, selectively highlight the features of interest in the image or suppress some unwanted features in the image, so that the image matches the visual response characteristics. Image enhancement can be divided into two categories: frequency domain methods and spatial domain methods. The frequency domain method regards the image as a two-dimensional signal, and performs signal enhancement based on two-dimensional Fourier transform. The low-pass filtering method can remove the noise in the picture; the high-pass filtering method can enhance high-frequency signals such as edges and make blurred pictures clear. The representative algorithms in the space do...
