Ex 1 P3

Beitrag von Dragon » 5. Nov 2008 11:54

I don't clearly understand the last task on the exercise sheet (image sharpening).

What are the two finest levels of the laplacian pyramid?
Are these the images with the highest resolution? :?:

Is it right only to multiply the finest to level matrices by a scalar to amplifie them?
The image my perhaps get sharper but also lighter doesn't it?

You are supposed to do sharpening using the high frequency sub bands of the pyramid. The high frequencies you find in the high resolution images, correct.

Scaling up in this case means multiplying with some number, right. If you increase pixel values the image gets brighter, yes.
