  • Patent number: 10417779
    Abstract: Methods and systems are disclosed for deriving quantitative measurements of an imaged material using plenoptic imaging. In one or more embodiments, image data is generated by a plenoptic camera having a filter configured to transmit a plurality of different spectra in different regions of the filter. A set of plenoptic image data is produced by determining respective sets of pixels in the image data corresponding to the different regions of the filter and determining light intensities of the plurality of different spectra for respective super-pixel groups of the pixels in the image data. One or more additional quantitative measurements of an imaged material are then derived from a comparison of the determined light intensities of two or more of the plurality of different spectra.

  • Patent number: 10375418
    Abstract: There is a method of compressing image data comprising a set of image values each representing a position in image-value space so as to define an occupied region thereof. The method comprises selectively applying a series of compression transforms to subsets of the image data items to generate a transformed set of image data items occupying a compacted region of value space. The method further comprises identifying a set of one or more reference data items that quantizes the compacted region in value space. For each image data item in the set of image data items, a sequence of decompression transforms from a fixed set of decompression transforms is identified that generates an approximation of that image data item when applied to a selected one of the one or more reference data items. Each image data item in the set of image data items is encoded as a representation of the identified sequence of decompression transforms for that image data item.

  • Patent number: 10360666
    Abstract: An input HDR image may be represented using an SDR image and a modulation value. For the SDR image to be viewable and representative of the HDR image, we propose a mid-tone optimization technique to calculate the modulation value. In particular, we use two conditions when deriving the modulation value: (1) the blacks are not clipped down to zero too aggressively; and (2) the number of codewords in the SDR image used to represent the mid-tone range of the HDR image is maximized. The modulation value can further be clipped to avoid over-shooting in both very dark images and very bright images. Temporal stabilization can also be used to smooth temporal variations of the luminosity in the SDR video. After the modulation value is determined, the SDR image can be obtained based on the HDR image and the modulation value.
