用STM32F4芯片自带的DCMI摄像头接口驱动不带FIFO的OV7725摄像头，实现60HZ刷新率。imgprcs.c文件中包含大量的适用于嵌入式设备的高速图像处理算法，包括边缘提取、区域分割、颜色识别等等，全部使用自适应算法，适合不同光照和环境条件(With STM32F4 chip comes with DCMI camera interface driver without FIFO OV7725 camera, to achieve 60HZ refresh rate. The img

利用stm32f4采集ov2640摄像头图像，将图像二值化处理后，得到黑白图像，再经过算法，识别出图像的形状，目前可以识别：正方形、三角形、圆形(Using stm32f4 to capture ov2640 camera image, the image two value processing, get black and white images, and then through the algorithm to identify the shape of the image, can
