基于改进的空间域变换的图像增强算法研究

Image Enhancement Algorithm Based on the Improved Spatial Domain Transform

为了提高图像增强后的图像质量,提出了一种改进型的图像增强算法,首先对图像进行傅里叶变换,然后对图像进行直方图修正,采用高斯平滑滤波处理技术,最多得到清晰图像。实验结果表明,提出的改进算法有效地提高了图像的清晰度,图像增效效果更为平滑。

in this paper, in order to improve the image of enhanced image quality, proposed one kind based on the improved spatial domain transform image enhancement algorithm. Method based on image transform, then the image histogram correction, using Gauss filter processing technology, up to get a clear image. The experimental results show that the proposed algorithm effectively improves the image resolution, image synergistic effect is more smooth.
