摘要: Temperature imaging has been recognized to improve a variety of diagnostic and interventional procedures and to predict and prevent failures of electrical circuits and equipments. A system design and method is disclosed, wherein the thermal data is fused and mapped with the data streams coming from a US, CT, or MR scanner, giving the doctors or industrial investigators the impression of being working with a known US, CT, or MR system which has been augmented by the temperature mapping capability.

摘要: A multi-frequency microwave antenna (1) of the microwave image reconstruction system senses a signal which passes through an analogue connection (6) to a Dicke null-balancing radiometer (7) which detects sequentially the signal contributions at the different frequencies of the multi-frequency antenna of the system. The resulting sequential analogue signals from the radiometer are directly related to the brightness temperatures at the corresponding frequencies, and these brightness temperatures are directly related to a real intra-body temperature distribution. The system uses a PC (5) and comprises a mean to reconstruct a one-dimensional profile of real intra-body temperatures from the brightness temperatures via the outputs from the analogue-to-digital converter (15). The algorithm of this system uses “large” over-complete dictionaries which, on the one hand reflect the variability of potential temperature profiles and on the other hand incorporate as much a-priory information as possible, in order to provide reliable image reconstruction.

摘要: A mark is incorporated to the original during the fabrication of said original in such a way that said mark is invisible on the original but appears on the copy of the original which is made by using a photocopying machinge. The mark is incorporated by additionally mixing the original image to be protected and the marking image to be concealed in the original by modulating one or the other of the images or by manipulation of Fourier transforms.

摘要: An automatic testing method and device is described that can test a video sequence coder/decoder system and either assess the quality of decoded sequences or rate the fidelity of the coding chain. The device produces synthetic test patterns that induce the appearance of known artifacts, then tracks and evaluates such artifacts. Based on this evaluation, it can rate the system's performance in a way that correlates well with human assessments. In our testing device, the quality estimation module performs this function.
