概要

• 論文の詳細を見る

• The matrix whose eigenvectors are the basis vectors of the DCT is introduced. This matrix leads to a convolution-product property using the DCT. Based on the property, the parameter of uniform blur, such as motion blur or out-of-focus blur, is estimated from the local minima of the DCT energy spectrum of a blurred image. Computer experiments confirmed that the DCT is superior to the DFT for estimating the parameter.
