Detailed Description
template<typename Tdata>
class ebl::camera_shmem< Tdata >
The camera_shmem class interfaces with camera images that come from a shared buffer in memory. It allows to grab images from a shared buffer in the idx format, and also to save gui outputs into video files.

Initialize shmem camera using a shared memory descriptor. height and width are optional parameters that resize the input image to those dimensions if given (different than -1). One may want to decrease the input resolution first to speed up operations, for example when computing multiple resolutions.
- Parameters:
-
shmem_path The path id of the shared memory. height Resize input frame to this height if different than -1. width Resize input frame to this width if different than -1.
