1. A method for generating a projection image of a three-dimensional sample, the method comprising:
obtaining a set of images of the sample, wherein each image of the set of images corresponds to a respective focal plane within the sample;
applying a filter to each image of the set of images to determine a respective depth value for each pixel of a depth map, wherein the depth value represents a depth, within the sample, at which contents of the sample can be imaged in-focus, and wherein applying the filter to each image of the set of images comprises, for a particular pixel of the image, determining a weighted measure of texture of a set of pixels in a neighborhood of the particular pixel for determining which pixels within the set of images are in focus to thereby generate the projection image of the three-dimensional sample; and
determining an image value for each pixel of an output image based on the depth value of a corresponding pixel of the depth map.
