OpenCV Resize Image - 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).
function_name - (Required, ForceNew) function name. gpu_memory_size - (Optional) The GPU memory specification of the function, in MB, is a multiple of 1024MB. handler - (Required) entry point of function. initialization_timeout - (Optional, Computed) max running time of initializer. initia...
