Method and System for Automatic Detection and Segmentation of Tumors and Associated Edema (Swelling) in Magnetic Resonance (Mri) Images
First Claim
1. In a data processing system, a method for segmenting an object represented in one or more input images, each of the one or more input images comprising a plurality of pixels, the method comprising the steps of:
- aligning the one or more input images with one or more corresponding template images each comprising a plurality of pixels;
extracting features of each of the one or more input images and one or more template images; and
classifying each pixel, or a group of pixels, in the one or more input images based on the extracted features of the one or more input images and the one or more corresponding template images in accordance with a classification model mapping image properties or features to a respective class so as to segment the object represented in the one or more input images according to the classification of each pixel or group of pixels.

Abstract
A method and system for segmenting an object represented in one or more input images, each of the one or more input images comprising a plurality of pixels. The method comprising: aligning the one or more input images with one or more corresponding template images each comprising a plurality of pixels; extracting features of each of the one or more input images and one or more template images; and classifying each pixel, or a group of pixels, in the one or more input images based on the measured features of the one or more input images and the one or more corresponding template images in accordance with a classification model mapping image properties or features to a respective class so as to segment the object represented in the one or more input images according to the classification of each pixel or group of pixels.

40. A data processing system for segmenting one or more input images into objects, each of the one or more input images each comprising a plurality of pixels, the data processing system comprising:
-
a display, one or more input devices, a memory, and a processor operatively connected to the display, input devices, and memory; the memory having data and instructions stored thereon to configure the processor to; align the one or more input images with one or more corresponding template images each comprising a plurality of pixels; measure features of each of the one or more input images and one or more template images; and classify each pixel, or a group of pixels, in the one or more input images based on the extracted features of the one or more input images and the one or more corresponding template images in accordance with a classification model mapping image properties or features to a respective class so as to segment the object represented in the one or more input images according to the classification of each pixel or group of pixels.

43. In a data processing system, a method for segmenting an object represented in one or more images, each of the one or more images comprising a plurality of pixels, the method comprising the steps of:
-
measuring image properties or extracting image features of the one or more images at a plurality of locations; measuring image properties or extracting image features of one or more template images at a plurality of locations corresponding to the same locations in the one or more images, each of the template images comprising a plurality of pixels; and classifying each pixel, or a group of pixels, in the one or more images based on the measured properties or extracted features of the one or more images and the one or more template images in accordance with a classification model mapping image properties or extracted features to respective classes so as to segment the object represented in the one or more images according to the classification of each pixel or group of pixels.
