In image processing, the free boundary condition is the convention used when applying a convolution kernel to a digital image in which pixel locations that lie outside the image boundaries are interpreted as having a value of zero.[https://engineering.purdue.edu/~bouman/grad-labs/Image-Filtering/pdf/lab.pdf] The question of what value to assign out-of-bounds pixels may arise, for instance, when applying a 3×3 kernel to the corner pixel in an image. {{DEFAULTSORT:Free Boundary Condition}}{{Compu-graphics-stub}} 1 : Image processing |
