运动目标检测算法（Matlab）

function varargout = object_detect(varargin) % OBJECT_DETECT MATLAB code for object_detect.fig % OBJECT_DETECT, by itself, creates a new OBJECT_DETECT or raises the existing % singleton*. % % H = OBJECT_DETECT returns the handle to a new OBJECT_DETECT or the handle to % the existing singleton*. % % OBJECT_DETECT('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in OBJECT_DETECT.M with the given input arguments. % % OBJECT_DETECT('Property','Value',...) creates a new OBJECT_DETECT or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before object_detect_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to object_detect_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
