WebIn 2D, pixel position represents the center of the bottom-left pixel. In 3D, pixel position corresponds to the center of the bottom-left front pixel. PixelValue gives the value of the pixel nearest to {xp, yp}, except that when the position {xp, yp} lies on a boundary between pixels, the average of the pixels surrounding {xp, yp} is returned. WebWrite an image series as JPEG. The WriteImage function receives a volume and a list of images names and writes the volume according to the z axis. For a displayable result we need to rescale the image intensities (default is [0,255]) since the JPEG format requires a cast to the UInt8 pixel type. In [21]:

An entire class of operations on binary images operates on a 3×3 window of the image. This contains nine pixels, so 2 or 512 possible values. Considering only the central pixel, it is possible to define whether it remains set or unset, based on the surrounding pixels. Examples of such operations are thinning, dilating, finding branch points and endpoints, removing isolated pixels, shifting the image a pixel in any direction, and breaking H-connections.
