       abstract = {The sliding window approach is the most widely used technique
to detect an object from an image. In the past few years, classifiers
have been improved in many ways to increase the scanning speed. Apart
from the classifier design (such as cascade,',','),
 the scanning speed also depends
on number of different factors (such as grid spacing, and scale at
which the image is searched). When the scanning grid spacing is larger
than the tolerance of the trained classifier it suffers from low detections.
In this paper we present a technique to reduce the number of miss detections
while increasing the grid spacing when using the sliding window
approach for object detection. This is achieved by using a small patch
to predict the bounding box of an object within a local search area. To
achieve speed it is necessary that the bounding box prediction is comparable
or better than the time it takes in average for the object classifier
to reject a subwindow. We use simple features and a decision tree as
it proved to be efficient for our application. We analyze the effect of
patch size on bounding box estimation and also evaluate our approach
on benchmark face database (CMU+MIT). We also report our results on
the new FDDB dataset [1]. Experimental evaluation shows better detection
rate and speed with our proposed approach for larger grid spacing
when compared to standard scanning technique.},
