Abstract: A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths.

Abstract: The invention describes a method and a microscopy system for imaging and analyzing stochastically and independently blinking point-like emitters. A multiple-order cumulants analysis in conjunction with an established blinking model enables the extraction of super-resolved environment-related parameter maps, such as molecular state lifetimes, concentration and brightness distributions of the emitter. In addition, such parameter maps can be used to compensate for the non-linear brightness and blinking response of higher-order cumulant images—used for example in Super-resolution Optical Fluctuation Imaging (SOFI)—to generate a balanced image contrast. Structures that otherwise would be masked by brighter regions in the conventional cumulant image become samples using spectral cross-cumulants.

Abstract: A method for coding includes; segmenting an image into blocks; grouping blocks into a number of subsets; coding, using an entropy coding module, each subset, by associating digital information with symbols of each block of a subset, including, for the first block of the image, initializing state variables of the coding module; and generating a data sub-stream representative of at least one of the coded subsets of blocks. Where a current block is the first block to be coded of a subset, symbol occurrence probabilities for the first current block are determined based on those for a coded and decoded predetermined block of at least one other subset. Where the current block is the last coded block of the subset: writing, in the sub-stream representative of the subset, the entire the digital information associated with the symbols during coding of the blocks of the subset, and implementing the initializing sub-step.

Abstract: A multiscale telescopic imaging system is disclosed.

Abstract: Coding techniques for a video image compression system involve improving an image quality of a sequence of two or more bi-directionally predicted intermediate frames, where each of the frames includes multiple pixels.

The brightness values of the pixels in at least one of the non-bidirectionally predicted frames is converted from a non-linear representation.
