👉 Outthrobs are a type of digital signal processing technique used in computer vision and image recognition. It is named after its main component, which is an out-of-band (OOB) channel that is not present in the actual data stream but rather sent to the receiver as an output. In other words, it's like sending a message without actually hearing it because the sender has already transmitted it. This technique allows for processing of digital signals at low power levels without any interference from external noise or errors
