How to use PARALLELdn operator after RemoveImage gracefully to reduce parallelism without having to use frame buffer?
For example, the input parallelism is 4, and now RemoveImage is used to delete three images in a continuous sequence of four images and only one is retained. The remaining processing logic is actually sufficient when the parallelism is 1. We use PARALLELdn to reduce the parallelism to 1 in order to reduce resources, but must we use a frame buffer for this? After all, even if one image cannot be transmitted in time after the parallelism is reduced to 1.
