A multi-scale modeling method for thermal-degraded image

Content-based adaptive image denoising using spatial information

“…2(a). Therefore, to achieve good visual image quality, we adopt a weighted average method to splice the sub-blocks as in [19,36]. More precisely, we firstly extend the overlapped region to form a transition region, then construct weight coefficients according to the distance between the block boundary and the pixels in the transition region, lastly splice the adjacent blocks together through these weight coefficients.…”

“…On the other hand, for our region spatial adaptive purpose, it is more convenient and computationally cheaper to identify the local spatial information in each block than by a pixelwise region segmentation algorithm for the same purpose [18]. For more information about block-based image processing, please refer to [8,17,19,20,36]. This paper is organized as follows.…”
