Abstract: Methods and systems for reducing the required footprint of SNoW-based classifiers via optimization of classifier features. A compression technique involves two training cycles. The first cycle proceeds normally and the classifier weights from this cycle are used to rank the Successive Mean Quantization Transform (SMQT) features using several criteria. The top N (out of 512 features) are then chosen and the training cycle is repeated using only the top N features. It has been found that OCR accuracy is maintained using only 60 out of 512 features leading to an 88% reduction in RAM utilization at runtime. This coupled with a packing of the weights from doubles to single byte integers added a further 8× reduction in RAM footprint or a reduction of 68× over the baseline SNoW method.

Abstract: There is provided a driving support apparatus. A recognition controller determines whether an object detected by processing a captured image by an object detection unit is a smoke-like object or not in a smoke-like object determination unit. When the detected object is determined to be the smoke-like object, the recognition controller checks a range distribution in a region of the smoke-like object, adds the result as attribute information of “density”, and transmits the resultant to a controller.

Abstract: A method of restricting turns at vehicle intersections imposes a policy that is dynamic and congestion based. Vehicle turns are allowed only to the extent that such a maneuver does not cause a hindrance to other vehicles traveling the same direction that are not turning.

In this way, such a “no hinder” turn restriction is dependent on actual driving conditions and allows for more efficient movement of traffic in both heavily congested and light driving conditions. A no hinder turn restriction may be combined with or may replace other types of turn restrictions and may be utilized for both left and right turns and for streets with single or multiple lanes.
