  • Correlation image detection | TechLink
    and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8594457 Status Active Categories Photonics Sensors Software Information Technology A correlation image detection method is provided that co registers sonar images by finding peaks in correlation images To obtain the peaks the mean of the absolute values of the correlation coefficients in the correlation image is found and the Rayleigh parameter is determined from the mean Based on the Rayleigh parameter an appropriate threshold can be determined using a desired probability of false detection The threshold can be chosen such that the probability of a single false detection over the expected life of the mission for which correlation detection is being performed is extremely low The peak value in the image is determined and a correlation is considered detected when the peak value is greater than the product of the threshold and the Rayleigh parameter If a detection occurs the correlation image detector returns the transformation that co registers the two images USPTO url http patft uspto gov netacgi nph Parser Sect1 PTO1 Sect2 HITOFF d PALL p 1 u Facebook Twitter Google Plus LinkedIn Main menu Home Licensing Joint R D

  • Method of estimating blur kernel from edge profiles in a blurry image | TechLink
    Managers at http techlinkcenter org about staff Patent Identifier 8594447 Status Active Categories Software Information Technology A method of deblurring a two dimensional blurred image An edge within the blurred image is detected and an edge profile of the blurred image is extracted A length of the edge profile is determined and a blur kernel size is estimated based thereon A quantile function is applied to the edge profile thereby generating quantile function output A linearity test is performed on the quantile function output thereby obtaining a preliminary linearity metric Another quantile function is selected and the applying a quantile function to the edge profile thereby generating quantile function output and the performing a linearity test on the quantile function output thereby obtaining a preliminary linearity metric is iteratively repeated until a best linearity metric a best quantile function and a best quantile function output are determined A slope of the best quantile function output is determined and a blurring parameter is determined based thereon A blur kernel is estimated based on the blurring parameter and the blur kernel size A sharp image is resolved using the blur kernel USPTO url http patft uspto gov netacgi nph Parser Sect1 PTO1

  • Computationally Efficient Method for Image Segmentation with Intensity and Texture Discrimination | TechLink
    http techlinkcenter org about staff Patent Identifier 20130308830 Status Active Categories Software Information Technology A computationally efficient image segmentation method is provided that processes a grayscale digital image to more clearly show textures in the underlying object shown in the digital image A grayscale digital image is converted to an intensity matrix based on the brightness of the pixels in the image where each matrix element represents a pixel in the digital image and has a value corresponding to the intensity i e the brightness of that pixel The value of each matrix element is compared to the value of its nearest neighbor matrix element and the pixel represented by the matrix element is categorized as being dark or bright based on its value and is categorized as being smooth or rough based on the values of the nearest neighbor matrix elements As each pixel is categorized it is assigned a shading level corresponding to the brightness texture matrix element value A processed image having only the assigned shading levels is then produced with the processed image indicating textures of the underlying object shown in the original grayscale digital image USPTO url http appft uspto gov netacgi nph Parser Sect1
