Modification of fastNlMeansDenoising
function for colored images.
cv2.fastNlMeansDenoisingColored(src[, dst[, h[, hColor[, templateWindowSize[, searchWindowSize]]]]]) → dst{% endblock %} {% block parameters %}
src
.h
value perfectly removes noise but also removes image details, smaller h
value preserves details but also preserves some noise. Default value is 3.h
but for color components. For most images value equals 10 will be enough to remove colored noise and do not distort colors. Default value is 3.searchWindowsSize
- greater denoising time. Recommended/Default value 21 pixels.
The function converts image to CIELAB colorspace and then separately denoises L and AB components with given h
parameters using fastNlMeansDenoising
function.
