I need to know if it influences the performance of the algorithm in order to classify do more concatenation or not do concatenations of LBP from regions of the image.
I would like to classify a large dataset of images, I have read in some articles that it divide each image into several sub-block and then extracted the texture improve the classification.
Is partition the image useful for classification process in the case of LBP?
I have been studying some modification to LBP in order to discriminate more kind of texture. Some of them are based on making the LBP less sensitive to noise. Henrique what other feature you see usefull to concatenate with LBP histogram?.
What I meant was concatenating other texture descriptors like BGP or even LPB at a different scale, and also concatenating color features like an RGB or HSV miniature of the image in raster format. You can also play with PCA if you need a more compact combined descriptor.
There is always a trade-off between geometric invariance and having finer blocks over which LBP pattens can be computed and concatenated. If the texture patterns exhibit a lot of geometric transformations( rotations, scale, etc) beyond a point going for more detailed LBP may not help.
