图像处理方法和图像处理装置具有校正像素统计值以减少随机噪声

Image processing method and image processing device with correction of pixel statistical values to reduce random noise
Abstract:
The present invention is a method including: correcting difference between a pixel statistical value of a specific layer and a pixel statistical value of a layer that is wider than the specific layer using an edge information of a layer that is wider than the specific layer; correcting the pixel statistical value of the specific layer using post-correction difference and the pixel statistical value of layer that is wider than the specific layer; recorrecting the post-correction pixel statistical value of the specific layer using difference between a pre-correction pixel statistical value of the specific layer and the post-correction pixel statistical value of the specific layer and the edge information of a layer that is wider than the specific layer; and correcting the target pixel by repeating correction and recorrection until the layer reduces its range from the maximum range to the minimum range.
Abstract(Chinese):

本发明是一种方法，包括：使用比特定层宽的层的边缘信息来校正特定层的像素统计值和比特定层宽的层的像素统计值之间的差; 使用校正后差异和比特定层宽的层的像素统计值来校正特定层的像素统计值; 使用特定层的校正前像素统计值和特定层的校正后像素统计值之间的差以及比该特定层的修正后像素统计值更宽的层的边缘信息之间的差异来重新校正特定层的校正后像素统计值 特定层; 以及通过重复校正和重新校正来校正目标像素，直到该层将其范围从最大范围减小到最小范围。
