Publication number: 20210284184Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining a point cloud augmentation policy and training a machine learning model using the point cloud augmentation policy to perform a perception task such as object detection or classification task by processing point cloud data. In general, training a machine learning model using the determined point cloud augmentation policy enables the model to more effectively perform the perception task, i.e., by generating higher quality perception outputs. When deployed within an on-board system of a vehicle, the machine learning model can further enable the on-board system to generate better-informed planning decisions which in turn result in a safer journey, even when the vehicle is navigating through unconventional environments or inclement weathers such as rain or snow.Type: ApplicationFiled: March 5, 2021Publication date: September 16, 2021Inventors: Yang Song, Shuyang Cheng, Zijian Guo, Congcong Li, Chunyan Bai

Quantification of optical absorption coefficients using acoustic spectra in photoacoustic tomography
Patent number: 9655527Abstract: Accurately quantifying optical absorption coefficient using acoustic spectra of photoacoustic signals. Optical absorption is closely associated with many physiological parameters, such as the concentration and oxygen saturation of hemoglobin, and it can be used to quantify the concentrations of non-fluorescent molecules. A sample is illuminated by, for example, a pulsed laser and following the absorption of optical energy, a photoacoustic pressure is generated via thermo-elastic expansion. The acoustic waves then propagate and are detected by a transducer. The optical absorption coefficient of the sample is quantified from spectra of the measured photoacoustic signals. Factors, such as system bandwidth and acoustic attenuation, may affect the quantification but are canceled by dividing the acoustic spectra measured at multiple optical wavelengths.Type: GrantFiled: June 11, 2015Date of Patent: May 23, 2017Assignee: Washington UniversityInventors: Lihong Wang, Zijian Guo -
