易于分割的一种图像重构方法

A method of image reconstruction for easy segmentation

在自然环境光下获取的图像 ,由于光照方向、强度、不均匀性的不断变化导致很大的不一致 ,给图像分割带来极大的困难 ,为此提出了一种易于实现图像分割的重构方法 .该方法首先分离出图像的边缘部分与平滑部分 ,再按一定规则重构图像 。

The image captured in the nature environments is always corrupted due to the unequal illumination in different direction. The most obvious effect is that the contrast between the objects and the backgrounds differs greatly, which makes the segmentation of the image quite difficult. This paper presents a new method of segmentation based on image reconstruction. The detail and background parts in the original image are extracted respectively by convoluting the original image with a smoothing function. A new image is acquired by combining the two parts of the original image according to certain rules. Since the unequal illumination effect is greatly reduced in the reconstructed image, the segmentation result is quite satisfied.
