Patent number: 10244263Abstract: Methods of data encoding using trees formed with logic gates are described which lead to spatial compression of image data. Data encoding is achieved using a five-level wavelet transform, such as the Haar or the 2/10 transform. A dual transform engine is used, the first and engine being used for the first part of the first-level transform, the second part of the first-level transform and the subsequent-level transforms being performed by the second transform engine within a time interval which is less than or equal to the time taken by the first transform engine to effect the part-transform. Each bit plane of the resulting coefficients is then encoded by forming a tree structure from the bits and OR logical combinations thereof. Redundant data are removed from the resulting tree structure, and further data can be removed by using a predetermined compression profile.Type: GrantFiled: October 20, 2015Date of Patent: March 26, 2019Assignee: RGB SYSTEMS, INC.Inventor: Peter Lionel Smith

Patent number: 9992252Abstract: The present invention is a method and apparatus for adaptively compressing and transmitting streaming video, preferably implemented in hardware as part of a codec, that adaptively applies a variable rate of compression to images in a video stream to optimize the quality attainable for a given transport bandwidth. In one or more embodiments, image frames from the video stream are divided into blocks, and a variable compression ratio compression engine compresses the blocks for transmission over a network. Depending on their compressed sizes, one or more of the compressed blocks are packaged into fixed size data packets for transmission over a network. The data packets are fed into a packet buffer. A packet servo releases packets from the buffer to achieve a desired transport data rate. The amount of compression applied by the compression engine is controlled based on the number of packets in the buffer.Type: GrantFiled: September 29, 2015Date of Patent: June 5, 2018Assignee: RGB SYSTEMS, INC.Inventor: Peter Lionel Smith

Patent number: 7379626Abstract: An edge adaptive system and method for image filtering. The method maps each output pixel onto input image coordinates and then prefilters and resamples the input image pixels around this point to reduce noise and adjust the scale corresponding to a particular operation. Then the edge in the input image is detected based on local and average signal variances in the input pixels. According to the edge detection parameters, including orientation, anisotropy and variance strength, the method determines a footprint and frequency response for the interpolation of the output pixel. In a more particular implementation, the method divides the input pixel space into a finite number of directions called skews, and estimates the edge orientation with the nearest skew direction. This further facilitates pixels inclusion in the interpolation of the output pixel.Type: GrantFiled: August 20, 2004Date of Patent: May 27, 2008Assignee: Silicon Optix Inc.Inventors: Vladimir Lachine, Gregory Lionel Smith, Louie Lee

Patent number: 7359575Abstract: Dynamic warp map generation system and corresponding method are disclosed. A compactor obtains spatial transformation parameters along with geometric and optical distortion parameters and combines them to form hybrid grid data in a hybrid vector space. This vector space is divided into hybrid blocks. In each hybrid block, the grid dataset is fitted with a hypersurface and the surface coefficients are saved in an interface. A decompactor obtains dynamic control parameters representing varying distortion parameters and generates a hybrid space vector. According to the hybrid space vector, a warp map is decoded from the hypersurface coefficients that compensates for dynamic geometric and optical distortions. In another example of the present invention, the dynamic warp map generation system is used for color gamut transformation.Type: GrantFiled: December 7, 2004Date of Patent: April 15, 2008Assignee: Silicon Optix Inc.Inventors: Zorawar S.

Patent number: 7277187Abstract: A system and method for dimensioning large or palletized freight of one or more pieces determines the dimensions of a rectangular prism having the smallest volume which would contain the freight. The system is capable of being positioned remotely from the freight. The system is further configured to determine the dimensions in varying levels of ambient light and varying object surface reflectance. The system still further is configured to first rapidly scan an area to determine the general location of the boundaries of the freight and then more precisely scan the determined general boundaries of the freight to determine the precise boundaries of the freight.Type: GrantFiled: July 1, 2002Date of Patent: October 2, 2007Assignee: Quantronix, Inc.Inventors: Melvyn Lionel Smith, Lyndon Smith, Eve Carlsruh

Patent number: 7239360Abstract: A short throw projection system and method for displaying a corrected optical image on a projection screen based on input image data that includes an electronic correction unit, an image projector and a reflection assembly. The electronic correction unit receives the input image data and generates pre-distorted image data. The image projector receives the pre-distorted image data from the electronic correction unit and projects a pre-distorted optical image that corresponds to the pre-distorted image data or a pre-distorted image compensated by the projection optic distortion. The optical reflection assembly is positioned in the optical path of the pre-distorted optical image to project an optical image on the projection screen. The reflection assembly can consist of various combinations of curved and planar mirrors as desired.Type: GrantFiled: June 12, 2003Date of Patent: July 3, 2007Assignee: Silicon Optix Inc.Inventors: Zorawar S.

Patent number: 7064770Abstract: A method and system for circularly symmetric anisotropic filtering over an extended elliptical or rectangular footprint in single-pass digital image warping are disclosed. The filtering is performed by first finding and adjusting an ellipse that approximates a non-uniform image scaling function in a mapped position of an output pixel in the input image space. A linear transformation from this ellipse to a unit circle in the output image space is determined to calculate input pixel radii inside the footprint and corresponding filter coefficient as a function of the radius. The shape of the footprint is determined as a trade-off between image quality and processing speed. In one implementation, profiles of smoothing and warping components are combined to produce sharper or detail enhanced output image. The method and system of the invention produce natural output image without jagging artifacts, while maintaining or enhancing the sharpness of the input image.Type: GrantFiled: September 9, 2004Date of Patent: June 20, 2006Assignee: Silicon Optix Inc.Inventors: Vladimir Lachine, Gregory Lionel Smith, Louie Lee
