Output Original Dimensions : (149, 200, 4) Print('Resized Dimensions : ',resized.shape) Resized = cv2.resize(img, dim, interpolation = cv2.INTER_AREA) Height = int(img.shape * scale_percent / 100) Width = int(img.shape * scale_percent / 100) OpenCV uses the function to accomplish this task resize ().

Scale_percent = 60 # percent of original size OpenCV OpenCV comparison of interpolation algorithms when resizing an image tanveer222 2 months ago No Comments Resizing (scaling / scaling) is a very commonly used method when working with images. Print('Original Dimensions : ',img.shape) Img = cv2.imread('/home/img/python.png', cv2.IMREAD_UNCHANGED) We will use this scale_percent value along with original image’s dimensions to calculate the width and height of output image. Providing a value <100 downscales the image provided. In the following example, scale_percent value holds the percentage by which image has to be scaled.

Note that the initial dst type or size are not taken into account. Also, the aspect ratio of the original image. The function resize resizes the image src down to or up to the specified size. We will look into examples demonstrating the following resize operations. Resizing an image means changing the dimensions of it, be it width alone, height alone or changing both of them. Resizing an image can be done in many ways. INTER_CUBIC – a bicubic interpolation over 4×4 pixel neighborhood INTER_LANCZOS4 – a Lanczos interpolation over 8×8 pixel neighborhood But when the image is zoomed, it is similar to the INTER_NEAREST method. It may be a preferred method for image decimation, as it gives moire’-free results. INTER_NEAREST – a nearest-neighbor interpolation INTER_LINEAR – a bilinear interpolation (used by default) INTER_AREA – resampling using pixel area relation. flag that takes one of the following methods. The syntax of resize function in OpenCV is cv2.resize(src, dsize]]]) In this tutorial, we shall the syntax of cv2.resize and get hands-on with examples provided for most of the scenarios encountered in regular usage. To resize an image, OpenCV provides cv2.resize() function. Also, the aspect ratio of the original image could be preserved in the resized image. Resizing an image means changing the dimensions of it, be it width alone, height alone or changing both of them.
