for an image in size 480x640 after using extractLBPFeatures function, output is an 1*59 single. for training a neural network such as MLP, that is better input layer less than 59. how to reduce output.
img = imread('trainimage.jpg');
features = extractLBPFeatures(img);

You can reduce features by Principle Component Analysis (PCA).
in matlab there is pca() function. google it.
