Method for Generating a Result Image and Optical Device
An object (100) is illuminated sequentially using at least two illumination geometries (110-1, 110-2). An intensity image of the object (100) is captured for each one of the at least two illumination geometries (110-1, 110-2). The intensity images are combined for producing a results image. Combining is carried out in such a way that the results image satisfies a predetermined optimization criterion. By way of example, the optimization criterion may relate to an image contrast, an edge steepness or an image sharpness. Optimization may be carried out with a spatial resolution.
Super-resolution processing method for TV video images, super-resolution processing device for TV video images that is used in same method, first to fourteenth super-resolution processing programs, and first to fourth storage media
In order to solve the problems described above, the present invention employs a PSF restoring means and an image restoring means, implemented in software or hardware, for executing a plurality of iterations of real-number-based computations based on Bayse probability theory by using, as input information, a PSF luminance distribution identified according to a degree of degradation of TV video, a luminance distribution of a degraded image constituted of Y (luminance) components of the TV video, and an estimated luminance distribution of restored-image initial values. With these means, an estimated luminance distribution of a restored image having a maximum likelihood for the luminance distribution of the degraded image is obtained, and the estimated luminance distribution is substituted for the Y components of the TV video obtained by extracting the luminance distribution of the degraded image. Accordingly, TV video that approximates the pre-degradation state is provided substantially in real time.

AUTOMATED REGENERATION OF LOW QUALITY CONTENT TO HIGH QUALITY CONTENT
A system accesses content structure that includes a first attribute table including a first list of attributes of a first object, and a first mapping including first attribute values. The first list of attributes of the first object also includes a quality attribute indicating a first quality. After a request to modify quality is received, the system searches a plurality of content structures for a suitable second content structure that comprises a second attribute table including a second list of attributes of a second object. The suitable content structure has another attribute that matches a corresponding attribute of the first list of attributes of the first object and a quality attribute indicating a second quality. The system modifies the first attribute table to include the second list of attributes of the second object. In this way content is generated that is of higher or lower quality than the original content.
