掩模

The best digital tool to do this with is a function called an unsharp mask (available in programs such as PhotoShop).

最好的数字工具来做到这一点的是一个功能称为锐化掩模。

下一步所涉及的模糊，所以我首先然轻锐化掩模（ 30岁， 1.0 ， 0是一个良好的形象，这大小）对第一次。

The image enhancement after using wavelet unsharp masking to improve the edge and useful detail information are studied.

运用小波反锐化掩模法对图像的轮廓及细节信息进行增强处理，完成图像的最终增强。

In order to remove the disturbing noise embedded in the image,protect the edge and useful detail information,and improve the visual contrast effect,a new method for image enhancement based on rough sets and wavelet unsharp masking is presented.

为了有效去除图像中的干扰噪音，改善模糊不清晰的有用边缘细节信息，提高图像的层次感和清晰度，提出将粗糙集和小波反锐化掩模相结合的方法来实现图像增强。

A little more unsharp mask can be used with inkjet images as they are somewhat diffused in the printing process, hiding any small amounts of oversharpening.

有一点更锐化掩模可用于喷墨打印的图像，因为它们有一些分散在印刷过程中，隐藏任何少量的oversharpening 。

First, the color-image was preprocessed with grayscaling, smoothing. The vertical gradient components of the image were found using the vertical mask of Sobel operator. Then the candidate areas with sufficient amount of edges were determined by calculating the gradient of edges. After finding possible vehicle candidates, the proposed method measured the prominent vertical symmetry of candidate areas and verified all possible candidates, as symmetry is an important feature of vehicle. The proposed method also figured out the vertical axis of symmetry and the width of the candidate vehicle.

算法首先对图像进行灰度化、平滑去噪等预处理，使用Sobel算子垂直方向掩模计算图像感兴趣区域内的边缘梯度，确定候选区域；而后根据车辆图像垂直边缘具有对称性的特点，分析候选区域的对称性强弱，并计算其对称轴位置和车辆宽度。
