摘要： There is provided an image processing device capable of easily reducing a burden related to image recognition and obtaining stable recognition performance even when a posture of a vehicle changes from moment to moment. An image processing device 50 includes a storage unit 5 and an image processing unit 6. The storage unit 5 stores a pickup image acquired by an image pickup unit 4 mounted on the vehicle and an inclination angle transmitted from an inclination angle sensor 2 that detects the inclination angle of the vehicle. The image processing unit 6 performs image processing on the pickup image. The image processing unit 6 associates the pickup image in an inclined state with the inclination angle based on a time difference Δt between a time from when the pickup image in the inclined state is acquired by the image pickup unit 4 until the acquired pickup image is stored in the storage unit 5, and a time from when the inclination angle is detected by the inclination angle sensor 2 until the detected inclination angle is stored in the storage unit 5. The image processing unit 6 generates a recognition image in a non-inclined state, which is used for image recognition of the pickup image, from the pickup image in the inclined state based on the inclination angle associated with the pickup image.

摘要： Photoluminescence and electroluminescence are essential characterization techniques for photovoltaics cells and modules. For electroluminescence, the main technical challenge is easily injecting current into the photovoltaic to cause luminescence. The technique described herein enables daylight electroluminescence imaging without the need for external power sources. For photoluminescence, characterization is performed on photovoltaic cells, modules, strings, and arrays in daylight and without temporary mounting of LED modulators. Instead, the modulation is performed using a permanent electronic module installed within the electric circuit on the DC side. This enables automation or triggering of modulation on demand, 100% inspection without changes in hardware configuration because the cells are never shaded and provides a path to high throughput imaging.

摘要： Disclosed embodiments include methods and computer systems for brain image prediction or segmentation. A clinical image file of data representative of a patients' brain image, including structures of interest (SOI) such as the subthalamic nucleus (STN), is applied to and processed by a segmentation process. The segmentation process uses one or more machine learning approaches such as trained deep learning models to identify the SOI in the clinical image. Output by the segmentation process is a segmented image file of data representing the brain image in which the structures of interest (SOI) are segmented. By the segmentation process, the SOI in clinical image, including the locations, orientations and/or boundaries of the SOI, are accurately predicted or identified, and can thereby be presented in an enhanced visualization form (e.g., highlighted) in the segmented image.
