Abstract: Known super-resolution algorithms are inefficient due to a high degree of redundant calculations, require search operations such as block matching for finding nearest neighbors, and achieve only small magnification factors. An improved method for upscaling an image comprises steps of upscaling the image by pixel interpolation to obtain a coarse upscaled image, and, for each pixel of the coarse upscaled image, determining a nonlinear regression function for a patch of pixels around a current pixel of the coarse upscaled image and enhancing the value of the current pixel by adding the result of the nonlinear regression function, wherein a pixel of an upscaled image is obtained. The nonlinear regression function is obtained from a trained regression tree, based on geometric features of the patch.

Abstract: A 3D model can be modeled using “pattern-instance” representation, wherein an instance component may be represented as transformation (for example, rotation, translation, and scaling) of a pattern. Quantization errors may be introduced when encoding rotation information, causing different vertex coordinate errors at different 5 vertices of an instance. To efficiently compensate the vertex coordinate errors, the encoder decides a quantization parameter for compensating a vertex coordinate error. The quantization parameter is signaled in the bitstream as a quantization index. The quantization index, a quantization table the indicates a mapping between quantization indices and quantization parameters, and vertex coordinate errors are 10 encoded into a bitstream. The quantization table may be built based on statistical data. At the decoder, the vertex coordinate error is decoded based on a quantization parameter, which is determined from a received quantization index.

Abstract: A module includes a rectifier coupled to an input connector for rectifying an input alternating current (AC), mains supply voltage for a power supply regulator. The passive rectifier applies an input filtered direct current (DC) boosted supply voltage to the power supply regulator, when the filtered DC boosted supply voltage is selectively developed at the input connector. A first sensor senses when the filtered DC boosted supply voltage is selectively developed at the input connector. A switch reduces current loading at the input connector, when the filtered DC boosted supply voltage is developed at the input connector, but not when any of the AC mains supply voltage. An add-on power supply module includes a backup battery for developing the filtered DC boosted supply voltage, in substitution for the unfiltered rectified output supply voltage, when the AC mains supply voltage is unavailable.

Abstract: The invention relates to a method for bounding an object in a video sequence Fx,y,t. The method includes obtaining a subset of pixels located in the object to annotate, in each frame of the video sequence. Spatio-temporal slicing is performed on the video sequence Fx,y,t, centered on the obtained subsets of pixels, resulting in a first image Fy,t obtained by an horizontal concatenation of first slices, comprising the obtained subsets of pixels, and resulting in a second image Fx,t obtained by a vertical concatenation of second slices. A trajectory of the obtained subsets of pixels is displayed on both the first Fy,t and second Fx,t image. A bounding form around the object to annotate is obtained out of four points in each frame of the video sequence, wherein the coordinates of the four points of a frame t are obtained from the coordinates of the points located in the first and second boundary of the first and second image for that frame t.
