digital image processing

利用VB开发的推箱子小游戏，支持自定义地图及关卡。可完美编译运行，是学习游戏开发的好材料。

说明：  偏移程序，全部都经编译通过，希望给爱好的偏移的朋友已点帮助.(Migration process, all by compiled through, hoping to offset-loving friends have points to help.)

说明：  针对已知多频率正弦信号的频谱，设计相应的FIR滤波器(凯塞窗函数法设计低通,高通，带通滤波器，分别提取信号并绘制频域和时域曲线)按要求进行滤波。 根据已知滤波器的性能指标设计IIR数字滤波器(双线性变换法设计巴特沃斯低通IIR数字滤波器)，并对心电图信号进行滤波处理；(For known more frequency sinusoidal signal spectrum, to design the corresponding FIR filter (Kaiser window function method of designing low-pass, high-pass, band-pass filter, respectively, to extract the signal curve) and draw the frequency domain and time domain filtering according to the known filter in accordance with requirements of performance index design of IIR digital filter (bilinear transformation method to design butterworth low-pass IIR digital filter), and to filter the ecg signal)
