视频跟踪标记-SampleVideo.zip 简介 通过帧差法进行视频跟踪，并做标记。 代码 % By lyqmath @ Matlab中文论坛 clc; clear all; close all; avi = mmreader; for i = 1 : avi.NumberOfFrames img = read; pixels = img; figure; imshow; text, 'FontWeight', 'Bold', 'Color', 'r'); end tracking; 复制代码 function d = tracking if ischar % 载入视频数据 for i = 1 : avi.NumberOfFrames img = read; pixels = img; end else pixels = video; end nFrames = size; rows = size; cols = size; % 转换成灰度图像 for i = 1 : nFrames pixel = )); end for i = 2 : nFrames d = - pixel)); bw = im2bw, 0.2); % 寻找上下边界 cou=1; for h = 1:rows for w = 1:cols if bw > 0.5 bottomEdge = h; if cou == 1 topEdge = bottomEdge; end cou = cou 1; break; end end end % 寻找左右边界 coun=1; for w = 1:cols for h = 1:rows if bw > 0.5 rightEdge = w; if coun == 1 leftEdge = rightEdge; coun = coun 1; end break; end end end % 矩形框生成 wd = rightEdge-leftEdge; hg = bottomEdge-topEdge; widt = wd/2; heit = hg/2; cenx = leftEdge widt; ceny = topEdge heit; % 显示并标记 figure; imshow, []); hold on rectangle; plot; text, 'FontWeight', 'Bold', 'Color', 'r'); hold off end 复制代码 视频文件 SampleVideo.zip
