Convolutional sparse representations differ from the standard form of sparse representations in their composition from coefficient maps convolved with dictionary filters instead of linear combinations of dictionary vectors. When applied to images, the standard form is usually independently computed over a set of overlapping image patches. The advantage of the convolutional form is that it provides...
When applying sparse representation techniques to images, the standard approach is to independently compute the representations for a set of overlapping image patches. This method performs very well in a variety of applications, but results in a representation that is multi-valued and not optimized with respect to the entire image. An alternative representation structure is provided by a convolutional...
When applying sparse representation techniques to images, the standard approach is to independently compute the representations for a set of overlapping image patches. This method performs very well in a variety of applications, but the independent sparse coding of each patch results in a representation that is not optimal for the image as a whole. A recent development is convolutional sparse coding,...
