  • Publication number: 20170294017
    Abstract: Systems and methods for analyzing vessels in multiplexed images include detecting large vessels using a spoke feature detection method, detecting long and narrow vessels using a line feature detection method, detecting smaller vessels using rolling-ball filtering and binary image operations to generate a mask, and evaluating any contour polygons resulting from these operations using quality measurements and other thresholds. Maturity determination and nuclei detection are also performed, resulting in an output of vessel characteristics and co-locations enabling enhanced analysis of multispectral images.

  • Publication number: 20170080413
    Abstract: A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.

  • Publication number: 20170053397
    Abstract: Systems and methods for speeding up a spectral unmixing process by using pixel groups are disclosed. Operations including forming groups of similar pixels, and unmixing only one representative pixel from each pixel group enable determination of an unmixing result for all the pixels in the group. A similarity metric may be based on a dot product of an unprocessed pixel with the representative pixel in the subset of pixels. The method is repeated for any number of remaining unmatched pixels that exceed a threshold, until the number of remaining or unmatched pixels is smaller than the threshold, upon which the remaining pixels may be individually unmixed. Significantly fewer unmixing operations are performed on an image, thereby speeding up the unmixing process.
