We propose to use the partial similarity between a sample and a number of exemplars as the image features for visual object detection. Define a part of the object as a sub-window inside the object bounding box, for each part of the object, a codebook of local appearance templates is learned. By using multiple templates for each part, and allowing the template to be compared with a bag of part instances in the neighborhood of the canonical location, the deformable and multi-aspect properties can be captured. A linear classifier is learned with feature selection, selecting a subset of the templates. To improve the efficiency of the detector, a rejection cascade is built by calibrating the linear classifier; the rejection cascade makes decisions using partial scores. Experimental results show that our method substantially improves the performance for human detection.

The demographic evolution of most western developed countries show a progressive increase on population aged 65 and older. One of the consequences of this gradual ageing is the rise of expensive age-related disabilities. Elder dementia patients often get lost due to temporary lack of a sense of direction. This may put them at risk and cause their families much worry. Our project aims to provide mobility monitoring support for fast location and help in case of loss caused by elder temporary mental disabilities.
