Abstract: The present invention relates to an apparatus (10) for determining cellular composition in one or more tissue sample microscopic images. It is described to provide (210) first image data of at least one tissue sample. The first image data relates to a non-specific staining of a tissue sample of the at least one tissue sample. Second image data of the at least one tissue sample is provided (220). The second image data relates to specific staining of a tissue sample of the at least one tissue sample. Either (i) the tissue sample that has undergone specific staining is the same as the tissue sample that has undergone non-specific staining, or (ii) the tissue sample that has undergone specific staining is different to the tissue sample that has undergone non-specific staining. A non-specific cellular composition cell density map is determined (230) on the basis of the first image data. A specific cellular composition cell density map is determined (240) on the basis of the second image data. Information regarding cellular composition in the at least one tissue sample is determined (250) on the basis of the non-specific cell density map and the specific cell density map.

Abstract: An apparatus comprises a receiver (201) for receiving an image signal comprising a number of three dimensional images representing a scene from different viewpoints, each three dimensional image comprising a mesh and a texture map, the signal further comprising a plurality of residual data texture maps for a first viewpoint being different from the different viewpoints of the number of three dimensional images, a first residual data texture map of the plurality of residual texture maps providing residual data for a texture map for the first viewpoint relative to a texture map resulting from a viewpoint shift of a first reference texture map being a texture map of a first three dimensional image of the number of three dimensional images and a second residual data texture map of the plurality of residual texture maps providing residual data for a texture map for the first viewpoint relative to a texture map resulting from a viewpoint shift of a second reference texture map being a texture map of a second three dimensional image of the number of three dimensional images. A mesh processor (203) generates a first mesh for the first viewpoint and a second mesh for the first viewpoint from an additional reference mesh being a mesh of the second three dimensional image of the plurality of three dimensional images. A first texture processor (205) generates a first intermediate texture map in response to a viewpoint transformation of the first reference texture map from a viewpoint of the first three dimensional image to the first viewpoint and an second intermediate texture map in response to a viewpoint transformation of the second reference texture map from a viewpoint of the second three dimensional image to the first viewpoint. A second texture processor (207) generates a first texture map in response to a combination of the first intermediate texture map and the first residual data texture map, and a second texture map in response to a combination of the second intermediate texture map and the second additional residual data texture map. An image generator (209) generates an image for a second viewpoint from the first texture map, the first mesh, the second texture map, and the second mesh.

Abstract: An apparatus receives an image and an associated depth map comprising input depth values. A contour detector (405) detects contours in the image. A model processor (407) generates a contour depth model for a contour by fitting a depth model to input depth values for the contour. A depth value determiner (409) determines a depth model depth value for at least a one pixel of the contour from the contour depth model. The depth model may e.g. correspond to a single depth value which e.g. may be set to a maximum input depth value. A modifier (411) generates a modified depth map from the associated depth map by modifying depth values of the associated depth map. This includes generating a modified depth value for a pixel in the modified depth map in response to the depth model depth value. The depth model depth value may e.g. replace the input depth value for the pixel.

Abstract: An auto-stereoscopic display uses a steering backlight to enable individual views to be directed to desired locations corresponding to the position of the eyes of a viewer. However, a single (i.e. monoscopic) image is provided at large angles where the quality of an auto-stereoscopic image may drop below acceptable levels. This is achieved by addressing the light sources in the steering backlight as a function of angle.

Abstract: An apparatus comprises a first receiver (201) receives a real time image sequence of depth and/or visual data from an image sensor. A second receiver (209) receives a set of audio objects and metadata indicative of links between audio objects and material characteristics. An image generator (203) generates an output image sequence comprising an image object corresponding to a virtual scene object in the real world scene and a detector (205) detects an interaction between the virtual scene object and a real world scene object of a real world scene. An estimator (207) determines a material property for the real world scene object in response to image data of the sequence of image frames and a selector (211) selects an audio object in response to the material property and material characteristics linked to the set of audio objects. An output circuit (213) generates the output audio signal comprising the first audio object.

Abstract: A method is provided for selecting a transparency setting and color values of pixels in a virtual image. The virtual image can be formed by combining reference images taken at different angles to produce the virtual image that views an object at a new, uncaptured angle. The method includes determining for each pixel of the virtual image, what information it carries from the reference view images. The information of the pixel is used to define a pixel category, and the category is used to select, based on logical conditions, what information will be displayed by the pixel and to set the color of the pixels.

Abstract: A method for storing multi-view data with depth order data. The method comprises obtaining image frames of a scene from an imaging system with a plurality of cameras, obtaining depth maps from the imaging system and/or the image frames and obtaining qualitative depth information relating to the depth of at least one object present in the scene relative to other objects in the scene, the qualitative depth information being additional to the information conveyed by the depth map. A depth order is determined for a set of at least two objects present in the scene based on the qualitative depth information, wherein the depth order determines the depth of an object relative to other objects with different depth orders. The image frames of the scene, the corresponding depth maps and the depth order for the objects in the scene are then stored as the multi-view data.

Abstract: An image synthesis system comprises receivers (201, 203, 205) receiving scene data describing at least part of a scene; object data describing a 3D object from a viewing zone having a relative pose with respect to the object, and a view pose in the scene. A pose determiner circuit (207) determines an object pose for the object in the scene in response to the scene data and the view pose; and a view synthesis circuit (209) generates a view image of the object from the object data, the object pose, and the view pose. A circuit (211) determines a viewing region in the scene which corresponds to the viewing zone for the object being at the object pose. The pose determiner circuit (207) determines a distance measure for the view pose relative to the viewing region and changes the object pose if the distance measure meets a criterion including a requirement that a distance between the view pose and a pose of the viewing region exceeds a threshold.
