mosaic

I am doing some image enhancement experiments so I take photos from my cheap camera. The camera has mosaic artifacts and all images look like grid. I think pillbox (out-of-focus) kernel and Gaussian kernel would not be the best candidates. Any suggestions? EDIT : Sample I suspect this cannot be done via a constant kernel, because the effects on pixels are not the same (so there are "grids"). The effects are non linear. (And probably non-stationary), so you cannot simply invert the convolution and enhance the image -- if you could, the camera chip would do it on-board. The best way to work out

Here's how he is gonna make it: for each picture, he divides the picture into n x n cells, where each cell is assigned a color value. Then he chooses a cell, and checks the color values in the L x L region whose center is at this specific cell. Assuming the maximum and minimum color values in the region is A and B respectively, he will replace the color value in the chosen cell with floor(

I have just received the following design for a project, for an image grid gallery, with dynamic width & height images (user submitted images). (Screenshot at the end of post) I have tried jQuery Masonry , Tympanus Automatic Image Montage and CSS-Tricks Seemless Responsive Photo Grid , but each has their limitation. Jquery Masonry allows for both width and height to be dynamic, however there are gaps generated The latter 2 scripts, generate very nice grids, but with the problem that either width or height must be static EDIT: i came across, Isotope , which is almost perfect and i will probably

话不多说，先看例子， 外链 效果截图如下： 蚁行线 马赛克背景 代码： 蚁行线代码如下： /* <!-- HTML代码 --> <div class="ant"></div> */ /* 蚁行线动画 */ .ant { width: 200px; height: 200px; margin: 40px auto; border: 1px solid transparent; background: linear-gradient(white, white) padding-box, repeating-linear-gradient(-45deg, black 0, black, 25%, transparent 0, transparent 50%) 0% 0%; background-size: 6px 6px; background-position: 0% 0%; animation: ants 10s linear infinite; } @keyframes ants { to { background-position: 100% 100%; } } 马赛克代码： /* <!-- HTML代码 --> <div class="mosaic"></div> */ /* 马赛克背景 */ .mosaic { height: 285px; width: 495px;
