Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] figure 1 is an exemplary flowchart of the image enhancement method 10 according to an embodiment of the present invention.

[0031] Such as figure 1 As shown, the image enhancement method 10 includes an object detection step S11, an image enhancement parameter estimation step S12, an image enhancement step S13, an object detection step S14, and a stop condition judgment step S15. The input image first enters the object detection module S11 to detect objects in the image. Then, the image enhancement parameter estimation step S12 determines the image enhancement parameters based on the image features of the region containing the detected object, so that the image enhanced based on the image enhancement parameters will highlight the image fea...

Abstract

The invention provides an image enhancing method, an object detecting method and corresponding devices. The image enhancing method can comprise the following steps of: (a) selecting an image to be enhanced and detecting a specific object in the image; (b) determining image enhancing parameters based on characteristics of an image in an area containing the detected specific object to stand out the characteristics of the image in the area by the image which is enhanced based on the image enhancing parameters; (c) enhancing the image to be enhanced according to the determined image enhancing parameters; (d) detecting the specific object in the enhanced image; (e) judging whether a predetermined stopping condition is satisfied; if so, outputting the enhanced image which has the best object detecting result at present; or, selecting the enhanced image as the image to be enhanced and repeating the steps (b) to (e). The image enhancing parameters can be determined based on characteristics of the image in the area containing the detected object and a good object detecting result can be gradually obtained through iterating the enhanced image.

Description

technical field [0001] The present invention generally relates to image processing, and more particularly relates to an image enhancement method and device, and an object detection method and device. Background technique [0002] Image enhancement is often involved in image processing such as face detection, moving object tracking, etc. [0003] Image enhancement generally refers to enhancing the user's interest information in the image to make the original unclear image clear or emphasize some interesting features, suppress uninteresting features, improve image quality, enrich the amount of information, and enhance the image. Interpretation and recognition effects. [0004] Image quality issues are a major obstacle to object detection from images. In particular, for example, in a video conferencing system, there is a need to detect the position of a human face from a video image. However, when the lighting conditions in the meeting room are not good, the resulting image ...
