초록

Input data comprising a video signal is processed using a combination of a known image processing method to deblur, or sharpen, the image and convolution with Pixon짰 kernels for smoothing. The smoothing process utilizes a plurality of different size Pixon짰 kernels which operate in parallel so that the input data are convolved with each di...

청구항

We claim: 1. A method for high speed enhancement of a video image comprising: inputting a signal containing input data corresponding to a frame of the video image, the input data comprising a plurality of data points on a grid; convolving the input data with each kernel of a plurality of different sized kernels to generate a plurality of convolved data sets; determining a change in data between the input data and each convolved data set of the plurality; comparing the change to a fit criterion; selecting the broadest kernel of the plurality of differe...
