Abstract: A method and system is provided in a simulation platform for optimizing the extrinsic parameters of fisheye-lens cameras installed on a vehicle. A simulated vehicle is established according to vehicular characteristics of associated actual vehicle over the simulated platform, thereby a lot of simulated checkerboard calibration plates are placed surrounding the simulated vehicle. A lot of simulated fisheye-lens cameras are generated and mounted on the simulated vehicle based on intrinsic parameters associated with actual fisheye lenses, and fisheye images are derived by using the simulated fisheye-lens cameras, respectively. The initially extrinsic parameters of each of the simulated fisheye-lens cameras are calculated over the simulated platform by using the first characteristic points of its own first fisheye image. Those initially extrinsic parameters may be used to optimize stitching images of the vehicle-surrounding-view systems, or be used to calculate installation tolerances when disposing fisheye-lens cameras physically.

Abstract: A speaking practice system with redundant pronunciation correction is shown, which provides a goodness of pronunciation (GOP) evaluation system running on a data processing server to detect redundant pronunciation in an audio recording. The audio recording is recorded when the user reads a practice text aloud. According to the detected redundant pronunciations, the user is informed to make corrections.

Abstract: The present disclosure relates to a neural network image identification system and a neural network building system and method used therein. The neural network building method comprises: forming a combination sequence of instruction graphic tags according to a plurality of instruction graphic tags selected by a user and displayed on a screen; combining a plurality of program sets corresponding to the plurality of instruction graphic tags in an order identical to that of contents in the combination sequence of these instruction graphic tags, to generate a neural network program; and checking whether the combination sequence of instruction graphic tags conforms to one or more preset rules before the neural network program is compiled. Therefore, the neural network image identification system is configured to identify an image to be identified captured by an image capturing device, while the neural network image identification program for identifying images by the neural network image identification system can be built by the neural network building system in accordance with needs of users.

Abstract: A non-volatile memory apparatus includes an error checking and correcting (ECC) decoding circuit, a first cyclic redundancy check (CRC) circuit, a second CRC circuit, and an interface circuit. The ECC decoding circuit decodes an original codeword to obtain a decoded codeword. The interface circuit receives and provides a first data portion of the decoded codeword to a host. The first CRC circuit performs a first CRC on the first data portion and generates a check status message based on a relationship between a result of the first CRC and a first CRC code of the decoded codeword. The second CRC circuit performs a second CRC on the first data portion to generate a second CRC code. The second CRC circuit determines whether to further change the second CRC code to make the second CRC code not match the first data portion according to the check status message.

Abstract: A data storage system and a global deduplication method thereof are provided. The data storage system includes multiple storage devices and one dispatch device. The dispatch device divides an original data corresponding to a data writing request into at least one data chunk. The dispatch device performs a summary calculation on one data chunk, so as to generate a representative value. The dispatch device performs a first distribution calculation on the representative value, so as to determine a destination location corresponding to the representative value. The dispatch device transmits the data chunk and the representative value to at least one destination storage device among the storage devices through a communication network according to the destination location. The at least one destination storage device checks the representative value, so as to determine whether to store the data chunk in a storage space of the at least one destination storage device.
