Embodiment Construction

[0041] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0042] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0043] Such as figure 1 As shown, the image enhancement method described in the embodiment of the present invention includes:

[0044] In step S101, binary processing is performed on the original image, and the original image is divided into a background image and an ...

Abstract

The invention discloses an image enhancement method. The image enhancement method comprises steps that binary processing on original images is carried out, and the original images are segmented into background type images and target type images; according to the image types after segmentation, calculation processing on the images after segmentation is carried out through employing a corresponding scale retinex algorithm; double-side filtering processing on brightness images contained in the images after calculation processing is carried out, wavelet de-noising processing on reflection images contained in the images after calculation processing is carried out; the images after double-side filtering processing and the images after wavelet de-noising processing are merged, gamma correction is further carried out, and the images after enhancement are acquired. Two-scale transform is carried out, and reduction of convolutional calculation amount is facilitated; double-side filtering processing on the brightness images is carried out, wavelet de-noising processing on the reflection images is carried out, noise removal for the images is facilitated, and image detail loss is relatively small; gamma correction for the images after synthesis is carried out, and global image enhancement is facilitated.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image enhancement method, device and equipment. Background technique [0002] Image enhancement is aimed at the application of a given image, purposefully emphasizing the overall or local characteristics of the image, making the original unclear image clear or emphasizing some interesting features, and expanding the difference between different object features in the image , to suppress uninteresting features, improve image quality, enrich information, enhance image interpretation and recognition, and meet the needs of some special analysis. It can highlight certain areas of interest, reduce the impact of some useless information, improve the visual effect of the image, and increase the value of the image. Image recognition has been widely used in medical diagnosis, face recognition, remote sensing images and other fields. The classic image enhancement a...
