Download the following images to your local directory:
Use http://cmp.felk.cvut.cz/~wbsdemo/demo/ to obtain multiple correspondences
for the image pair. Estimate the image to image transformation H
.
Try to get the transformation as precise as possible.
Use the transformation H
to transform the original image to the picture of the photograph
on the table.
Estimate illumination in each pixel. First, average the intensities over a neighbourhood of each pixel (usue function
conv2
). Experiment with the size of the averaging area. Let A be the intensity function of the original image and At of the transformed image.
Estimate the illumination as Ilum = At ./ A
. [2 points]
Use the transformation H
to replace the photograph by a differen one. [1 point]
Apply the estimated illumination change. [2 points]
