Cv2. imwrite() method is used to save an image to any storage device. This will save the image according to the specified format in current working directory. Syntax: cv2.imwrite(filename, image)

OpenCV offers support for the image formats Windows bitmap (bmp), portable image formats (pbm, pgm, ppm) and Sun raster (sr, ras).

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2. imwrite() method is used to save an image to any storage device. This will save the image according to the specified format in current working directory.

As a first step, the OpenCV python library is imported.jpg" from the OpenCV samples. In order to do so, a call to the cv::imread function loads the image using the file path specified by the first argument. The second argument is optional and specifies the format in which we want the image.

To save ndarray as an image file, set the file path and ndarray object to cv2. imwrite() . The format of the image file is automatically determined from the file path extension.

Imread() Loads an image from a file. The function imread loads an image from the specified file and returns it. If the image cannot be read (because of missing file, improper permissions, unsupported or invalid format), the function returns an empty matrix ( Mat::data==NULL ).

OpenCV-Python is a library of Python bindings designed to solve computer vision problems.OpenCV-Python makes use of Numpy, which is a highly optimized library for numerical operations with a MATLAB-style syntax. All the OpenCV array structures are converted to and from Numpy arrays.
