The present disclosure is directed to methods and systems for fusing Phase Contrast Angiography (PCA) with anatomic images to create a perforator PCA (pPCA) data set. In the pPCA) method, vascular and anatomic information may be provided by different MRI sequences. A four-point acquisition scheme may be used for 3D PCA acquisition of vascular images. Anatomical MRI images are acquired and may be enhanced with image post-processing techniques. The vascular and anatomical images may be combined with image fusion to create a high resolution map of abdominal wall vasculature. This high resolution map visualizes not only the size and location of the DIEP perforators, but also their relationship with surrounding tissue, and the blood flow velocity within them. As such, the fused pPCA image has substantially higher SNR and CNR than CTA image of the same slice thickness.

Examples disclosed herein relate to an autonomous driving system in an vehicle. The autonomous driving system includes a radar system configured to detect a target in a path and a surrounding environment of the vehicle and produce radar data with a first resolution that is gathered over a continuous field of view on the detected target. The system includes a super-resolution network configured to receive the radar data with the first resolution and produce radar data with a second resolution different from the first resolution using first neural networks. The system also includes a target identification module configured to receive the radar data with the second resolution and to identify the detected target from the radar data with the second resolution using second neural networks. Other examples disclosed herein include a method of operating the radar system in the autonomous driving system of the vehicle.

Systems and methods for generation of images of a particular type from images of a different type are disclosed. In an embodiment, an agricultural intelligence computer system receives a first plurality of images of a first type and a second plurality of images of a second type. The first and second types may refer to variances in resolution, frequency ranges of frequency bands, and/or types of frequency bands used to generate the images. Based on the first plurality of images and the second plurality of images, the agricultural intelligence computer system generates a feature set dictionary comprising mappings from features of the first plurality of images to features of the second plurality of images. When the agricultural intelligence computer system receives a particular image of the first type, the agricultural intelligence computer system uses the received image and the feature set dictionary to generate an image of the second type.
