摘要： The invention concerns a method for determining the displacement of a pixel between first and second images, the first image representing further an object in a first scene from a given camera station, and the second image representing the same object in a second scene, said second scene being obtained from the first scene by moving the object in the first scene and/or by moving the camera station of the first scene. The method comprises an operation which consists in defining (in 76) the colour of at least one point of the object of the second scene based on the position of said point in the first image so that the colour of the pixel of the second image corresponding to said point indicates the position of said pixel in the first image.

摘要： There are several types of plenoptic devices and camera arrays available on the market, and all these light field acquisition devices have their proprietary file format. However, there is no standard supporting the acquisition and transmission of multi-dimensional information. It is interesting to obtain information related to a correspondence between pixels of a sensor of said optical acquisition system and an object space of said optical acquisition system. Indeed, knowing which portion of the object space of an optical acquisition system a pixel belonging to the sensor of said optical acquisition system is sensing enables the improvement of signal processing operations. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is thus introduce.

摘要： The present invention relates to method for storing and transmitting sparse matrices in compact way. When storing and manipulating sparse matrices on a device, it is beneficial and often necessary to use speciafized algorithms and data structures that take advantage of the sparse structure of the matrix. The trade-off is that accessing the individual elements becomes more complex and additional structures are needed to be able to recover the original matrix unambiguously.
The method according to an embodiment of the invention consists in storing indexes enabling to determine the position in the matrix of non-null elements in an ordered way so as to limit the amount of information to be encoded and thus reduce the amount of data to be transmitted. The encoded information are enough for enabling the reconstruction of the matrix on a receiver.
