'''Local binary patterns (LBP)''' is a type of [[visual descriptor]] used for classification in [[computer vision]]. LBP is the particular case of the Texture Spectrum model proposed in 1990.<ref>DC. He and L. Wang (1990), "Texture Unit, Texture Spectrum, And Texture Analysis", Geoscience and Remote Sensing, IEEE Transactions on, vol. 28, pp. 509 - 512.</ref><ref>L. Wang and DC. He (1990), "Texture Classification Using Texture Spectrum", Pattern Recognition, Vol. 23, No. 8, pp. 905 - 910.</ref> LBP was first described in 19951994.<ref>T.

Ojala, M. Pietikäinen, and D. Harwood (1996), "A Comparative Study of Texture Measures with Classification Based on Feature Distributions", Pattern Recognition, vol. 29, pp. 51-59.</ref> It has since been found to be a powerful feature for texture classification; it has further been determined that when LBP is combined with the [[Histogram of oriented gradients]] (HOG) descriptor, it improves the detection performance considerably on some datasets.<ref>"An HOG-LBP Human Detector with Partial Occlusion Handling", Xiaoyu Wang, Tony X. Han, Shuicheng Yan, ICCV 2009</ref> A comparison of several improvements of the original LBP in the field of background subtraction was made in 2015 by Silva et al.<ref>C. Silva, T. Bouwmans, C.
