Abstract
In a method for extracting texture features from a multichannel image, which comprises a plurality of pixels, information of at least two channels of the image is combined for each of the plurality of pixels, and one or several texture features are determined from the combined pixel information.
Claims7
Method for extracting texture features from an image, comprising a plurality of pixels, comprising:
- (a) for each of the plurality of pixels, comparing the pixel intensity of the pixel with a threshold to generate a binary mask, comprising a first binary value for every pixel when the pixel intensity exceeds the threshold, or a second binary value when the pixel intensity does not exceed the threshold;
- characterised in that
- the image is a multichannel image and the step (a) is repeated for each of the channels to generate a binary mask for each of the channels;
- and
- the method further comprises the following steps:
- (b) for each of the plurality of pixels of at least two different channels, logically combining the binary values for the pixel in the binary mask associated to the first channel with the binary value for the pixel in the binary mask associated to the second channel to obtain a binary interlevel image;
- and
- (c) determining one or several texture features from the binary interlevel image.
