US11387935B2 Error detection and correction by modulation quality in 5G/6G
Message failures due to noise and interference cause unnecessary delays and reduction in reliability in wireless networks. To detect, localize, and correct transmission faults in 5G and 6G networks, the receiver can measure the “modulation quality” of each message reference element, according to how closely the amplitude and phase match the amplitude and phase levels of the modulation scheme. If the message is faulted, the receiver can re-assign each message element with poor modulation quality to the adjacent states, or if necessary to each state in the modulation scheme, and may thereby find the correct message value in many cases. Certain zones around each modulation state can indicate how the message element has been distorted by interference, and thereby indicate where to search for the correct state of that message element. When implemented, message fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.

The present invention relates to verification of damage to vehicles. More particularly, the present invention relates to a universal approach to automated generation of a damage estimate to a vehicle using images of the vehicle and verification of a manually-generated damage repair proposals using the automatically generated damage estimate.Aspects and/or embodiments seek to provide a computer-implemented method of generating one or more repair estimates from one or more photos of a damaged vehicle and comparing the generated estimate(s) to one or more input repair estimates to verify the one or more input repair estimates.
US11386540B2 Image based counterfeit detection
Systems and methods for authenticating material samples are provided. Digital images of the samples are processed to extract computer-vision features, which are used to train a classification algorithm. The computer-vision features of a test sample are evaluated by the trained classification algorithm to identify the test sample.
US11386538B2 Image processing apparatus, image processing method, and storage medium
Provided are an image processing apparatus, an image processing method, and a storage medium that can determine an anomaly while reducing influence of an individual difference of images. The image processing apparatus includes: a first generation unit that generates a first estimation image including at least a predetermined region of an inspection target by using a part of an inspection image including the inspection target; a second generation unit that estimates a difference between the first estimation image and the inspection image to generate a second estimation image by using the part of the inspection image; a comparison unit that compares the first estimation image with the inspection image; and an output unit that outputs a comparison result obtained by the comparison unit, and the comparison unit compares a difference between the first estimation image and the inspection image with the second estimation image.
