A method for processing microscopy images captures, for each of a first microscopy slide and a second microscopy slide, a plurality of partial spectrum images under multiple optical configurations where each image captures a different portion of the spectrum of the slide. First and second partial spectrum images associated with different optical configuration are selected and used to reconstruct respectively a combined spectrum image of part of the first microscopy slide and a combined spectrum image of at least part of the second microscopy slide, thereby forming a first pair of partial spectrum images. The method determines a distortion map by aligning images derived from the first pair of the partial spectrum images.

A method of producing an image with a blurred background () from an initial image () and a depth map () identifying a foreground region () and a background region () of the image, said method comprising determining () an edge visibility measure () for one edge () in the depth map () by comparing () a pixel value () in the foreground with a pixel value () in the background, said edge visibility measure () distinguishing between the foreground () and the background (); applying () a spatially variable blur to the depth map () to produce a compositing matte (), dependent on the edge visibility measure (); applying () a blur to the background region () of the depth map (); and compositing () the blurred background image data () with the initial image () to produce the rendered image with the blurred background ().

Disclosed is a method of browsing a set of media items on a display device. A sequence of thumbnail images corresponding to a portion of the set are initially displayed in a looping arrangement. A first thumbnail image of the sequence is displayed at a size larger than other thumbnail images of the sequence. The first thumbnail image corresponds to a focus position in the sequence. The arrangement responds to a user scrolling action to replace display of a second thumbnail image adjacent to an insertion point in the displayed sequence with a third thumbnail image corresponding to a media item of the set not displayed prior to the user action. The method then updates the focus position and insertion point and replaces a display of the first thumbnail image with display of a fourth thumbnail image corresponding to the updated focus position.

Method of browsing media items using thumbnails

A method of removing an artefact from an image captured with a motion invariant camera is disclosed. The captured image is de-blurred using a spatially invariant blur kernel. An edge filter with a fixed offset is applied to the de-blurred image to identify the location of at least one artefact. A parameter is estimated based on a region either side of the identified location. The at least one artefact is removed from the de-blurred image using the parameter.
