Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. A system comprising:
a camera (1116);
a microphone array (1214);
a memory (1104, 1204) storing computer-executable instructions; and
a hardware processor (1102, 1202) coupled to the camera (1116) and the microphone array (1214), the hardware processor (1102, 1202) configured to execute the computer-executable instructions to:
acquire an image (300) using the camera (1116), wherein the image (300) comprises pixels arranged in rows and columns (300, 400);
determine one or more bounding boxes (404-410) corresponding to one or more users (1-4) depicted in the image (300);
determine a plurality of bins (450) associated with the image (400), wherein each of the plurality of bins is associated with one or more of the columns (400);
acquire a plurality of audio samples (1002) using the microphone array (1214);
determine sound source localization (SSL) pan angle values (1002) associated with one or more of the plurality of audio samples (1002);
determine, for respective SSL pan angle values (1002), one or more corresponding bins (450) of the plurality of bins (450);
increment a count of bin entries (606) for each of the one or more corresponding bins (450) that is associated with each respective SSL pan angle value (606);
determine a first range (616, 640, 650) for each bounding box of the one or more bounding boxes (404-410), the first range (616, 640, 650) indicative of pixels extending from a first column to a second column (400);
determine, for the each bounding box, the count of bin entries (618) associated with the first range (616, 640, 650) for the each bounding box (404-410);
determine a first bounding box (404-410) having a greatest count of entries (620); and
determine output data (620) indicative of the first bounding box (404-410).
