The present disclosure provides an apparatus and method for evaluate the quality of a three dimensional (3D) point cloud. The apparatus comprises an image segmenter to generate a segmented two-dimensional (2D) image for each of the plurality of images; a 2D mask generator to generate a 2D mask for each of the plurality of images from the 3D point cloud; a comparator to compare the segmented 2D image with the 2D mask to obtain a comparison result for each image; and an evaluator to evaluate the quality of the 3D point cloud based on aggregated comparison results for the plurality of images.

The present disclosure relates to a system and a method for extracting a computer readable code from a captured image of a mailpiece or parcel using downsampling and edge detection. The system can include a reader configured to capture an image of an item having a computer readable code positioned thereon and a processor in data communication with the reader. The processor can generate captured image data of the item including the computer readable code, downconvert the captured image data to generate a downconverted image data and detect an edge of the computer readable code. The processor can also identify a position of the computer readable code in the downconverted image data and store or process only the identified computer readable code.

A digital image processing apparatus for computing a baseline estimate of a digital input image is provided. The digital image processing apparatus is configured to obtain a digital intermediate image by downsampling the digital input image by a predetermined downsampling factor, and compute the baseline estimate based on the digital intermediate image.

An apparatus for scaling images is provided that includes at least two input ports, a scaling component coupled to the at least two input ports, the scaling component including a plurality of scalers, the scaling component configurable to map any scaler to any input port of the at least two input ports and configurable to map more than one scaler to any input port, and a memory coupled to the at least two input ports and to outputs of the plurality of scalers, the memory configured to store image data for each input port and scaled image data output by the plurality of scalers.

Disclosed herein is a full-screen display device capable of sufficiently securing light transmittance of a sensor area overlapping a sensor unit in a pixel array and minimizing deterioration in perceived image quality of the sensor area. The pixels are arranged in the sensor area overlapping the sensor unit in the pixel array of the full-screen display device such that the number of pixels gradually decreases from the outer periphery toward the center of the sensor area in units of masks, and the area of a transmission portion gradually increases from the outer periphery toward the center of the sensor area in units of masks.

The disclosure relates to method and system for image scaling. The method includes determining a nature of image scaling required to be performed on an input image based on a vertical scaling ratio and a horizontal scaling ratio and includes determining if the image scaling is an upscaling or a downscaling, a symmetric scaling or an asymmetric scaling. The method further includes determining an overall scaling ratio based on a lower or an equal of the vertical scaling ratio and the horizontal scaling ratio. The method further includes scaling an input image to a target image using a polyphase finite impulse response (FIR) scaling filter based on the nature of the image scaling, the overall scaling ratio, and a structure of the polyphase FIR scaling filter. The scaling includes dynamically performing at least one of duplication of lines, addition of filler lines, duplication of pixels, and addition of filler pixels.

Disclosed herein includes a system, a method, and a device for improving computational efficiency of deconvolution by reducing a number of dot products. In one aspect, an input image having a set of pixels is received. A first dot product may be performed on a subset of the set of pixels of the input image and a portion of a kernel, to generate a first pixel of an output image. A number of multiplications performed for the first dot product performed may be less than a number of elements of the kernel. A second dot product on a remaining portion of the kernel to generate the first pixel of the output image may be bypassed.

A method for generating an image of a scene with a corresponding depth map is disclosed herein. The method comprises collecting a plurality of copies of a two-dimensional image of the scene, generating an intermediate image by concatenating the plurality of copies of the two-dimensional image along a first direction, generating an intermediate depth map corresponding to the intermediate image by applying a neural network to the intermediate image, and generating, from the intermediate image and the intermediate depth map, the image of the scene with the corresponding depth map.

A magnified portion and an unmagnified portion of a computer-generated reality (CGR) environment are displayed from a first position. In response to receiving an input, a magnified portion of the CGR environment from a second position is displayed with a magnification less than that of the magnified portion of the CGR environment from the first position and a field of view greater than that of the magnified portion of the CGR environment from the first position. A first unmagnified portion of the CGR environment from a third position is displayed with a field of view greater than that of the magnified portion of the CGR environment from the second position. Then, a second unmagnified portion of the CGR environment from the third position is displayed with a field of view greater than that of the first unmagnified portion of the CGR environment from the third position.

A method involves receiving a color video signal having a first frame rate. The color video signal is pre-processed to produce a pre-processed color video stream. The pre-processed color video stream is transformed into a monochromatic sketch stream. The first frame rate of the sketch stream is adapted to a second frame rate in accordance with dynamics of objects in a scene and are encoded to produce an encoded sketch stream. Frame-hints are produced using the pre-processed color video stream and are encoded to produce encoded frame-hints. The encoded sketch stream is multiplexed with the encoded frame-hints and service data to produce multiplexer output data which is transmitted via a communication channel or stored in a data storage system.
