  • Patent number: 11061767
    Abstract: A system and a method are disclosed for error correction during operations of a memory system. For example, during a read operation, the error correction includes a read retry determination to account for link errors that are detectable by cyclic redundancy check (CRC) but not correctable by error correction coding (ECC). Reducing the number of read retry operations performed may improve system performance by reducing the number of clock cycles spent on retry operations that could have otherwise been allocated for other system services (e.g., completing read and write operations). Additional CRC calculations and checks may be used to determine when to perform a retry in addition to existing CRC and ECC checks, reducing the number of potential retry operations and improving system performance.

  • Patent number: 11042157
    Abstract: According to some embodiments, a system pre-processes, via a first thread, a captured image perceiving an environment surrounding the ADV obtained from an image capturing device of the ADV. The system processes, via a second thread, the pre-processed image with a corresponding depth image captured by a ranging device of the ADV using a machine learning model to detect vehicle lanes. The system post-processes, via a third thread, the detected vehicle lanes to track the vehicle lanes relative to the ADV. The system generates a trajectory based on a lane line of the tracked vehicle lanes to control the ADV autonomously according to the trajectory.

  • Publication number: 20210183038
    Abstract: In an approach for object detection with missing annotations under visual inspection, a processor receives an image. A processor classifies the image being a not-good image using a pre-trained classifier. A not-good image means one or more defect objects being in the image. A processor, in response to classifying the image being the not-good image, detects the one or more defect objects in the not-good image. A processor masks the one or more defect objects in the not-good image. A processor inputs the masked image to train a detector.

  • Patent number: 11030738
    Abstract: A method, a device and a computer program product for image processing are proposed. In the method, whether a first image indicates a defect associated with a target object is determined. In response to determining that the first image indicates the defect, a second image absent from the defect is obtained based on the first image. The defect is identified by comparing the first image with the second image. In this way, the defect associated with the target object in the image can be accurately and efficiently identified or segmented.
