颅脑影像处理中的亮度变换方法及实现

摘 要:改善图像质量,使低对比度的图像得到增强. 利用Mat lab工具箱函数，采用灰度直方图均衡的方法对脑颅图像进行增强处理，取得了较好的效果. 用直方图均衡化的算法，将原始图像密集的灰度分布变得比较稀疏,处理后的图像视觉效果得以改善. 直方图均衡化则使不易观察到的细节变得清晰. 使用Mat lab工具箱大大简化了编程工作，为图像处理提供了一种技术平台.
请各位朋友帮帮忙，我们后天就要答辩了

Abstract: The improvement picture quality, enable the low contrast gradient the image to obtain the enhancement. Using the Matlab toolbox function, uses the gradation histogram balanced method to carry on enhancement processing to the skull image, has obtained the good effect. With the histogram equalizing algorithm, becomes quite sparse the primitive image crowded gradation distribution, after the processing image vision effect can improve. The histogram equalizing causes the detail which not easy to observe to become clear. Used the Matlab toolbox to simplify the programming work greatly, has provided one kind of technical platform for the imagery processing.
