Duplicate frame detection in multi-camera views for autonomous systems and applications

A processor comprising:

• one or more processing units to perform operations comprising:
• determining an expected sequence number corresponding to an output frame, the output frame generated from a plurality of input frames corresponding to one or more views and captured using one or more cameras, wherein consecutive input frames captured by the one or more cameras are associated with different sequence numbers;
• sampling, from each of one or more pixels included in the output frame, a pixel value stored in an alpha pixel channel associated with the pixel;
• performing, for each of the one or more pixels included in the output frame, a comparison of the expected sequence number to the pixel value stored in the alpha pixel channel associated with the pixel, wherein a position of at least one of the one or more pixels corresponds to a position within a display device that is visible to a user;
• based at least on the comparison, determining that the pixel value is outside of a predetermined threshold of the expected sequence number;
• and
• performing a safety action comprising at least preventing the output frame from being presented on the display device.

A system comprising:

• one or more processing units configured to:
• determine an expected sequence number corresponding to an output frame generated from a plurality of input frames that depict one or more views captured using one or more cameras;
• sample, from each of one or more pixels included in the output frame, a pixel value stored in an alpha pixel channel associated with the pixel;
• and
• determine whether to cause presentation of the output frame on a display device based on a comparison of the expected sequence number with one or more pixel values stored in alpha pixel channels associated with the one or more pixels included in and sampled from the output frame, wherein the comparison is based at least on a predetermined threshold, and a position associated with at least one of the one or more pixel values corresponds to a location within the display device that is visible to a user.
