Noise-free test images

Noise-free test images

During my PhD I created the following image dataset to evaluate noise estimation and denoising algorithms.
These images were taken with good lighting conditions and low ISO speed. Their original size was 3522x2348 pixels and each block of 5x5 pixels at each original image was substituted by its mean, giving the final 704x469 images you can find here. The subsampling reduced by a factor of 5 the noise level, making it negligible.

These images are widely used in our articles and are freely available to anyone who wants to use them if the source is acknowledged (that is, M. Colom).
