Publication number: 20230401420Abstract: A system receives a neural network model that includes asymmetric operations. Each asymmetric operation includes one or more fixed-point operands that are asymmetrically-quantized from corresponding floating-point operands. The system compiles a given asymmetric operation of the neural network model into a symmetric operation that includes a combined bias value. A compiler computes the combined bias value is a constant by merging at least zero points of input and output of the given asymmetric operation. The system then generates a symmetric neural network model including the symmetric operation for inference hardware to execute in fixed-point arithmetic.Type: ApplicationFiled: June 12, 2022Publication date: December 14, 2023Inventors: Chih-Wen Goo, Pei-Kuei Tsung, Chih-Wei Chen, Mingen Shih, Shu-Hsin Chang, Po-Hua Huang, Ping-Yuan Tsai, Shih-Wei Hsieh, You Yu Nian

Patent number: 10001856Abstract: Techniques pertaining to dynamic enablement, disablement and adjustment of offset of a virtual periodic timing control signal based on one or more predefined events are described. A method may determine whether a first predefined event is beginning. The method may also enable an offset of the virtual periodic timing control signal for synchronizing one or more first system modules in response to a determination that the first predefined event is beginning. The one or more first system modules may be configured to control one or more operations of one or more second system modules. The one or more second system modules may be configured to process one or more image frames. The method may further determine whether the first predefined event is ending. The method may additionally disable the offset in response to a determination that the first predefined event is ending.Type: GrantFiled: April 19, 2016Date of Patent: June 19, 2018Assignee: MEDIATEK INC.Inventors: Po-Hua Huang, Hsueh-Bing Yen, Chiung-Fu Chen

Publication number: 20160366323Abstract: Methods and systems for improving images and video captured by a device is provided. The methods and systems may involve a virtual 3D model for a scene that is in view of a device's sensors. The virtual 3D model may be generated using the sensor information and be used to produce a 2D lighting image. The lighting image may be applied to a captured image of the scene to improve lighting of the captured image or video. A virtual light source may be implemented as part of the process, which if desired, can be moved, adjusted, or modified in the virtual 3D model to adjust the lighting image and consequently adjust alighted image or a final image.Type: ApplicationFiled: March 31, 2016Publication date: December 15, 2016Inventors: Cheng-Che CHAN, Cheng-Che CHEN, Po-hua HUANG
