Texture Detail

Texture detail is one of the criteria for judging the quality of an image. Loss of image texture detail also implies the loss of some high-frequency information in areas with dense textures.

Texture detail is sometimes mistakenly identified as image noise and may be erroneously removed from the image. This can be an issue in low-light imaging, where analog and digital gain applied to image processing increases undesirable noise. As a result, noise reduction is used to smooth out the noise, but this can also, to some extent, erase detail.

Compare the phenomenon of texture detail and its degradation (as shown in the above and below images), the left image is part of a camera shot that has not been altered, while the right image is the same image after being processed by a noise reduction algorithm. Observe the loss of detail in the leaves in the right image, whereas the left image retains more texture detail. However, note that the edges of the color targets in both images remain unaffected by the noise removal algorithm.
