我需要一个可以将lbp图像转化成lbp分布直方图的matlab函数

以下是一个可以将LBP图像转化为LBP分布直方图的MATLAB函数：

function lbp_hist = lbp_histogram(lbp_image, num_bins)
% LBP_HISTOGRAM generates an LBP distribution histogram
%   lbp_hist = LBP_HISTOGRAM(lbp_image, num_bins) generates an LBP distribution
%   histogram from an LBP image. The histogram is normalized to sum to 1.
%
%   lbp_image:      The input LBP image
%   num_bins:       The number of histogram bins to use

% Calculate histogram bins
bin_edges = linspace(0, 255, num_bins+1);

% Calculate LBP histogram
lbp_hist = histcounts(lbp_image, bin_edges, 'Normalization', 'probability');
end

使用方法：

% Load image and extract LBP
img = imread('example.jpg');
lbp_img = extract_lbp(img);

% Generate LBP histogram with 8 bins
lbp_hist = lbp_histogram(lbp_img, 8);
