OpenCV用于读取和写入图像文件的分析处理

OpenCV读写图像文件解析

imdecode

从内存中的缓冲区读取图像。

C++: Mat imdecode(InputArray buf, int flags)

C++: Mat imdecode(InputArray buf, int flags, Mat* dst)

C: IplImage* decode_image(const CvMat buf*, int isColor=CV_LOAD_IMAGE_COLOR）

C: CvMat* cvDecodeImageM(const CvMat* buf, int iscolor=CV_LOAD_IMAGE_COLOR)

Python: cv2.imdecode(buf, flags) → retval

Parameters:

· buf – An input byte array or vector.
· flags – Same flags used as in the imread() function.
· dst – Optional output placeholder for decoded matrix: it helps save image reallocations during repeated calls to the function for images of identical
