Methods, systems, and devices for image processing are described. A device may support various filtering models relating to multidimensional graphics. The device may identify a target texel having a texel coordinate in an image, determine a set of neighboring texels based on the texel coordinate of the target texel, determine color values of multiple neighboring texels of the set of neighboring texels, compare the color values of the multiple neighboring texels of the set of neighboring texels, and process the target texel based on the comparing. In processing the target texel, the device may determine that the multiple neighboring texels may have same color values based on the comparing. The device may bypass a filtering operation on the target texel based on the multiple neighboring texels having the same color values. In an example of bypassing the filtering operation, the device may maintain a color value of the target texel.
