  • Patent number: 11037331
    Abstract: A method for de-contouring a source image is provided. In the method, a reference image is obtained based on the source image. Multi-oriented gradient calculation is performed on each pixel of the reference image, so as to obtain, for each pixel of the reference image, multiple gradient features that respectively correspond to multiple directions. For each pixel of the reference image, a monotonicity index is determined based on the corresponding gradient features. Then, a detail-protecting and de-contour operation is performed on the source image based on the monotonicity indices determined for the pixels of the reference image.

  • Patent number: 10984593
    Abstract: Techniques for designing and optimization of solid/cellular structures are described using a modeling process referred to as high-definition cellular level set in B-splines (HD-CLIBS). With this process, the entire design domain for the solid/cellular structure in question is subdivided into a set of connected volumetric cells in three dimensions. An implicit trivariate B-spline function is defined on each subdomain cell. With this parameterization scheme, constraints can be imposed on the relevant B-spline coefficients to naturally maintain geometric continuities at the connection faces between neighboring cells. The method offers several useful properties and powerful functionalities to build and modify a solid/cellular structure in the modeling process and to conduct topology optimization by directly adjusting the B-spline coefficients. The model construction can be carried out using a fast B-spline interpolation, and the topology optimization can involve a sequence of discrete B-spline convolutions.

  • Patent number: 10341671
    Abstract: An image compression method includes compressing an input image with first and second compression methods to generate first and second (e.g., lossless and lossy) compressed images. First and second residual layers are generated, based on a difference between the first and second compressed images. Connected components in the residual layers are identified. Each connected component includes a group of one or more pixels that, when mapped to the second compressed image is connected, in first and second directions, to pixels in the second compressed image. A compressed image is generated, which includes, for a connected component identified in the first residual layer, removing corresponding pixels from the second compressed image, and for a connected component identified in the second residual layer, adding corresponding pixels to the second compressed image. The system and method can thus provide file size savings associated with lossy compression while avoiding character replacement.

  • Patent number: 9965865
    Abstract: Devices and techniques are generally described for segmentation of image data using depth data. In various examples, color image data may be received from a digital camera. In some examples, depth image data may be received from a depth sensor. In various examples, the depth image data may be separated into a plurality of clusters of depth image data, wherein each cluster is associated with a respective range of depth values. In some further examples, a determination may be made that a first cluster of image data corresponds to an object of interest, such as a human subject, in the image data. In various examples, pixels of the first cluster may be encoded with foreground indicator data. In some further examples, segmented image data may be generated. The segmented image data may comprise pixels encoded with the foreground indicator data.

  • Patent number: 9860441
    Abstract: A computing device may obtain a first captured image of a scene and a second captured image of the scene. For a plurality of m×n pixel tiles of the first captured image, the computing device may determine respective distance matrixes. The distance matrixes may represent respective fit confidences between the m×n pixel tiles and pluralities of target p×q pixel tiles in the second captured image. The computing device may approximate the distance matrixes with respective bivariate surfaces. The computing device may upsample the bivariate surfaces to obtain respective offsets for pixels in the plurality of m×n pixel tiles. The respective offsets, when applied to pixels in the plurality of m×n pixel tiles, may cause parts of the first captured image to estimate locations in the second captured image.

  • Patent number: 9838681
    Abstract: Provided is an apparatus that includes an inverse scanning unit configured to an inverse scan pattern to the quantized coefficient components to generate a quantized block, an inverse quantization unit configured to generate a quantization parameter and to inverse-quantize the quantized block to generate a transformed block, an inter prediction unit configured to derive motion information and to generate a prediction block, and an adder configured to generate a reconstructed block. The transform unit is larger than a 4×4 block, each of the quantized coefficient components are inversely scanned in the unit of subset to generate multiple subsets, and the multiple subsets are inversely scanned to generate the quantized block. Accordingly, the coding efficiency of the motion information is improved by including various motion vector candidates. Also, the amount of coding bits of the residual block is reduced by applying diagonal scan pattern to each subset.

  • Patent number: 9733071
    Abstract: In the field of methods of three-dimensional measurement of an object by stereo-correlation, methods require at least two cameras connected to image processing means. These methods include at least a first step of calibration of the two image planes and a second step of spatial matching between these two image planes. These two steps can be followed by a third step of temporal matching. The method provided requires objects, the surface of which has a parametric representation, i.e. a mathematical representation of the object surface having the form of a decomposition over a scalar function basis. The parametric representation is implemented during the first calibration step and/or during the second and third steps of spatial or temporal matching.

  • Patent number: 9654776
    Abstract: In one example, an apparatus includes a video encoder configured to partition a block of video data into a first geometric partition and a second geometric partition using a geometric motion partition line, wherein the block comprises N×N pixels, divide the block of video data into four equally-sized, non-overlapping (N/2)×(N/2) sub-blocks, and encode at least one of the sub-blocks through which the geometric motion partition line passes using a transform size smaller than (N/2)×(N/2). The video encoder may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks. In one example, a video decoder may inverse transform the sub-blocks, and may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks.
