Please consider the following points: | |||
* Image Type: This refers to whether the input and output images use the '''lp/allocators/cudaimage.hpp''' library (images allocated in '''GPU memory''') or the '''lp/image.hpp''' library (images allocated in '''CPU memory'''). In the results, it is evident that processing time is higher when using an Image compared to a CudaImage. This difference arises because although the engine wrapper accepts both types of images, when using an Image, the engine internally creates a copy of the CPU memory to perform operations on the GPU. This copying process consumes considerable time compared to using an image already allocated in GPU memory. | |||
* PTZ Usage: This indicates a change in the pan, tilt, or zoom property before processing the input image. Consequently, the engine wrapper executes an additional step to calculate the output image, leading to an increase in processing time. | |||
