Operators

These are the operators included as part of the Holoscan SDK:

• aja_source: support AJA capture card as source

• bayer_demosaic: perform color filter array (CFA) interpolation for 1-channel inputs of 8 or 16-bit unsigned integer and outputs an RGB or RGBA image

• format_converter: provides common video or tensor operations in inference pipelines to change datatypes, resize images, reorder channels, and normalize and scale values.

• holoviz: handles compositing, blending, and visualization of RGB or RGBA images, masks, geometric primitives, text and depth maps

• multiai_inference: perform AI inference

• multiai_postprocessor: perform AI postprocessing

• ping_rx: “receive” and log an int value

• ping_tx: “transmit” an int value

• segmentation_postprocessor: generic AI postprocessing operator

• tensor_rt *(deprecated)*: perform AI inference with TensorRT

• video_stream_recorder: write a video stream output as .gxf_entities + .gxf_index files on disk

• video_stream_replayer: read .gxf_entities + .gxf_index files on disk as a video stream input
