Abstract: The disclosure provides a solution for intelligent machines, such as autonomous vehicles (AVs), that incorporate operating laws into motion planning by expressing complex operating laws along with other planning criteria under a single framework referred to herein as universal planning criteria (UPC). The UPC is expressed using a rule hierarchy approach, which allows for expressing individual operating rules, such as traffic rules, as signal temporal logic (STL) rules that are assigned an importance order. The STL rule hierarchy is advantageously equipped with a scalar rank-preserving reward function that can be differentiable and can be explicitly used for motion planning and/or embedding in neural motion planners. In one aspect the disclosure provides a method of operating an AV that includes: (1) scalably expressing traffic laws and additional planning criteria in a UPC framework, and (2) generating, using a neural motion planner and the UPC framework, a planned trajectory for the AV.

Abstract: Digital images, such as radiological images, are evaluated using correlative properties of information contained in a pixel and adjacent pixels. Each pixel is evaluated according to its own properties and adjacent pixels. Each pixel is identified as either satisfying a predefined criteria or not satisfying the criteria based on how many of the pixel and adjacent pixels satisfy a correlative property. A binary array is formed with the pixels satisfying the predefined criteria being nonzero and the other pixels being zero. The image being evaluated is divided into predefined blocks of pixels, and the number of nonzero pixels in each of the blocks is divided by the predefined number of pixels in the blocks to produce a ratio for each block. Image intensity is set for each of the blocks according to the ratio. Correlative information from corresponding pixels across different images of the same object can also be evaluated.
