  • Patent number: 11134276
    Abstract: A quantized image frame and a quantization of a high frequency image frame is obtained. The image frame is de-quantized and transformed to produce a low frequency image frame of a first color. A first set of components of the first color and a second set of components of the first color are determined based at least in part on the low frequency image frame and the high frequency image frame. The first set of components of the first color and the second set of components of the first color are combined with a set of components of a second color to produce a set of image data for an image frame. The set of image data is processed to produce the image frame in a particular format to be displayed on a display device.

  • Patent number: 11044404
    Abstract: A first image is aligned with a second image. A first motion value is computed based at least in part on a sum of differences between corresponding pixels in the first image and the second image. A second motion value is computed further based at least in part on a third image. An impact score is generated based at least in part on a difference between values derived from the first motion value and the second motion value and an action is performed depending at least in part on whether the impact score indicates that damage has occurred among objects represented in the first image and the second image.

  • Patent number: 10979737
    Abstract: A first set of components of a primary color and a second set of components of the primary color is extracted from image data. A low frequency image frame and a high frequency image frame is calculated based at least in part on the first set of components and the second set of components. The low frequency image frame is transformed and quantized to produce quantized data and residual data. The quantized data or the quantized data combined with the residual data, as determined based at least in part on a difference between the quantized data and previously output data, is stored in memory as at least a portion of an image frame in the memory. The image frame from the memory and a quantization of the high frequency image frame is provided to be displayed on a display device.

  • Patent number: 10939138
    Abstract: A quantized subset of set of image data is obtained. One or more iterations of inverse quantization are performed on the quantized subset until a de-quantized subset is produced that meets specified criteria. A block of an image frame is determined based at least in part on the de-quantized subset. The block is stored in a region of the memory allocated for storage of the block. A set of blocks that includes the block is output from the memory.

  • Patent number: 10872400
    Abstract: An image comprising a set of pixels is obtained and a dominant hue is determined. A color value of individual pixels in a subset of the set of pixels that fall within the hue range is modified to produce a first transformed image. A filter is applied to the first transformed image or an image derived from the first transformed image to reduce spatial high frequency noise and derive a low frequency image. A high frequency image is generated based on the first transformed image and the low frequency image. Whether the high frequency image depicts the object at a target image frequency is determined based on specified criteria for an object, and if the high frequency image corresponds to the target image frequency, the high frequency image is stored.

  • Patent number: 10594940
    Abstract: A first image and a second image recorded during a video capture event is obtained. A correction factor is computed based at least in part on a target interval and an interval of time between recording the first image and recording the second image. A motion value is computed based at least in part on a difference between the first region and the second region, with the first region and the second region both containing a reference object present in the first image and the second image. A normalized motion value is provided based at least in part on normalizing the motion value according to the correction factor.

  • Publication number: 20040156549
    Abstract: The quality of digital images recovered from compressed data in an inter-frame redundancy-removing scheme is enhanced using a self-adaptive feedback scheme in an image compression/decompression system so as to provide for the compensation of the distortion component from prior frame compression in subsequent difference frame compression. Each transmitted frame is stored after a full compress/decompress cycle, and difference data (which includes the inverse of the distortion component from compression of the transmitted frame) representing the difference between the stored frame and the incoming new frame is transmitted. Consequently, the quality of static regions in the recovered images may be improved with each subsequent iteration by taking the distortion component in the prior frame into consideration along with the inter-frame motion information. The feedback loop thus forms a self-adaptive iterative cycle.

  • Patent number: 6726680
    Abstract: A method, apparatus and system for template-controlled, precision laser interventions is described that greatly improves interventions such as laser microsurgery, particularly ophthalmic surgery, and industrial micromachining. The instrument and system are applicable to those specialties wherein the positioning accuracy of laser lesions is critical, such as whenever precise operations on a target or series of targets subject to movement during the procedure are to be effected. The system includes a user interface, wherein the user can either draw, adjust, or designate particular template patterns overlaid on a live video images of the target (such as the cornea) which are stabilized and produce an apparently stationary display of the target and provide the means for converting the template pattern into a sequence of automatic motion instructions to direct a laser beam to be sequentially applied replicating the designated template pattern into the corresponding surgical or industrial site.

  • Publication number: 20040059321
    Abstract: A method, apparatus and system for template-controlled, precision laser interventions is described that greatly improves the accuracy, speed, range, reliability, versatility, safety, and efficacy of interventions such as laser microsurgery, particularly ophthalmic surgery, and industrial micromachining. The instrument and system are applicable to those specialties wherein the positioning accuracy of laser lesions is critical, wherever accurate containment of the spatial extent of a laser lesion is desirable, and/or whenever precise operations on a target or series of targets subject to movement during the procedure are to be effected. A key object of the present invention is to implement a fully integrated approach based on a number of different instrumental functions all operating in concert within a single, fully automated unit. Each of the complementary, and at times competing, functions requires its own technologies and corresponding subassemblies.

  • Publication number: 20020118301
    Abstract: Method and apparatus for creating digital video effects on a frame of original image data containing pixel values. First spatial frequency banded frames are created from the frame of original image data, such that each spatial frequency banded frame contains pixels having pixel values defining an image of a different spatial frequency band of the original image data. At least some of the spatial frequency banded frames for different frames are then selectively processed to different extents. In this selective processing, the pixel values of all pixels in each spatial frequency banded frame are adjusted to the same extent. The processed spatial frequency banded frames for different spatial frequency bands are then combined to result in a processed frame having an image that is modified with respect to the original image data.
