How can I use the backpropagation algorithm of a multilayer neural network to enhance an image (e.g., my NN should work like a log transform)?

Please help me to find out whether back propagation in multi layer neural network can be trained to enhance an image… for e.g. there will be n no. of training images and expected result will be log transformed images…

is it possible to do so and how should i proceed ?

Pls help
