In this OpenCV tutorial, we learn the syntax of cv2.resize() and how to use this function to resize a given image. We can use cv2.resize() function to upscale, downscale, or resize to a desired size (considering or not considering the aspect ratio). OpenCV Python – Resize image Resiz...

OpenCV has a built-in function cv2.resize(), but we will perform transformation using matrix multiplication as previously. The matrix used for scaling is shown below:Sx and Sy are the scaling factors for the x-axis and y-axis, respectively....

方法二:缩放(Resize) 缩放也是使用opencv内置函数实现。 opencv提供了五种Resize方法: INTER_NEAREST - 最邻近插值 INTER_LINEAR - 双线性插值 默认 INTER_AREA - resampling using pixel area relation. INTER_CUBIC - 4x4像素邻域内的双立方插值 INTER_LANCZOS4 - 8x8像素邻域内的Lanczos插值 ...
