Following transformation sequence resizes images by the factor of 8, sets the value range to [400...4000], uses the *temperature* color model, and provides the image as a base64 encoded string.

#### Value Sampling #### Value Sampling
Following transformation sequence resizes images by the factor of 4, filters all values below 200 (considers values below 200 as noise), and provides the image in the raw format. The following transformation sequence resizes images by the factor of 4, filters all values below 200 (considers values below 200 as noise), and provides the image in the raw format.
This transformation could potentially also be used for other value forms than images. This transformation could potentially also be used for other value forms than images.
