英文翻译手机版

The traditional image enhancement approaches include gray - scale transformation , histogram modification , histogram equalization , image smoothing and wiener filtration
传统的图像增强方法有灰度变换、直方图修正、直方图均衡、图像平滑和维纳滤波。
For each gray image wavelet transform based on histogram modification is used to eliminate the disturbance of background . threshold , edge extraction , mathematics morphology methods are also used to process gray image
对于单幅灰度图，首先在直方图修正的基础上采用小波变换去噪技术，排除了背景图像噪声的干扰。
In this thesis , the preprocessing work includes histogram equalization and gray normalization . this preprocessing improves image quality , and eliminates the effects of illumination difference on the images
本论文在预处理阶段通过对灰度直方图修正、灰度归一等工作改善了原图像的质量,使光照不均匀对图像识别的影响降低。
Two methods , histogram equalization ( he ) and local area histogram equalization ( lahe ) , which are in common usage today , are not satisfactory if the image contains small , relatively uniform regions where exists objects or other details of interest
当我们感兴趣的信息包含在图像中相对较小且灰度分布较均匀区域时，两种广泛使用的直方图修正方法即直方图均衡( he )和局部直方图均衡( lahe )都不能增强这一部分信息。
