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.
• gxf_codelet: Provides a generic import interface for a GXF Codelet.
• holoviz: handles compositing, blending, and visualization of RGB or RGBA images, masks, geometric primitives, text and depth maps
• inference: performs AI inference using APIs from HoloInfer module.
• inference_processor: performs processing of data using APIs from HoloInfer module. In the current release, a limited set of operations are supported on CPU.
• 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
• test_ops : operators intended primarily for use in test cases. Currently contains a DataTypeTxTestOp which is a source operator which can be configured to emit data of many different basic C++ types. It also contains a DataTypeRxTestOp which receives via std::any and prints the type name of the received type. These are being used in Python test applications to test automated conversion from C++ types to/from equivalent Python types on receive or emit of various data types from a native Python operator. It also includes PoseTreeManagerLookupOp for validating fragment service lookup from C++ when a service is registered in Python.
• v4l2_video_capture: V4L2 Video Capture
• 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
