C# 클래스 Accord.Imaging.Filters.Blend

Linear Gradient Blending filter.

The blending filter is able to blend two images using a homography matrix. A linear alpha gradient is used to smooth out differences between the two images, effectively blending them in two images. The gradient is computed considering the distance between the centers of the two images.

The first image should be passed at the moment of creation of the Blending filter as the overlay image. A second image may be projected on top of the overlay image by calling the Apply method and passing the second image as argument.

Currently the filter always produces 32bpp images, disregarding the format of source images. The alpha layer is used as an intermediate mask in the blending process.
