I have a question on the output value of "extractLBPFeatures" function.
I run the following code, where Image is a 300 x 800 uint8 grayscale image.
lbp = extractLBPFeatures(Image,'Upright',false);
I got the output as
lbp = [0.0049327621 0.0095359785 0.011643226 0.032630574 0.051055972 0.032631438 0.015497292 0.0084941788 0.99728268 0.011309296]
I guess that the above numbers represent relative frequency, but the sum of these numbers are 1.175, which is more than 1. What exactly do these numbers represent?

The features returned by extractlbpfeatures encode local texture information, which you can use for tasks such as classification, detection, and recognition. For more details, refer - https://www.mathworks.com/help/vision/ref/extractlbpfeatures.html#buumhti-1-features.
Hope this helps.
