The processframe function is responsible for performing AI operations on the frame, such as object detection and pose estimation, and returning the results of those operations.

​
Function Defintion

The function accepts a single argument of type Frame. This object provides an easy-to-use interface to the Guru AI Platform. The remaining pages in this section document common types you can use with Frame.

/**
 * @param {Frame} frame - The frame to process
 * @return {*} - The output of processing for this frame.
 */
async function processFrame(frame) {
  return {};
}

class Frame {

  /**
   * Find objects of a specific type within the video.
   *
   * @param {(string|Array.<string>)} objectTypes - The type of the object to find.
   *    Can either be a string, in which case objects of a single type will be found, or an array of strings, in which case multiple object types will be found.
   * @param {boolean} keypoints - Flag indicating whether to include keypoints in the results. Defaults to true.
   * @return {Array.<FrameObject>} A list of FrameObject instances matching the given criteria.
   */
  async findObjects(objectTypes, {keypoints = true} = {});
}

Example

​
Find all of the people in the frame and outputs their location

async function processFrame(frame) {
  const objects = await frame.findObjects("person");

  return { people: objects };
}
