E. Weights Computation Based on Bounding Box

In this section shows that the knowledge of some prior information about the signal ft to be recovered enables to improve the quality of the reconstructed signal for the same number of random projections. Such prior information is introduced by means of a vector of weights w = [w(l) …w( -W)J , where w(i) denotes the weighting factor associated with the ith coefficient of the vector 6 = ФT ft in the 2-Dwavelet domain. Since 6j is not available, it propose to set the weights needed for the recovering of the foreground image at time t based on the estimated bounding boxes of the previous frame.

To be more precise, a window capturing the likely foreground position in the current frame is derived from the predicted bounding box positions and sizes. A window p is constructed on the basis of the pixel domain representation of the foreground image ft and next transformed to another window defined in the wavelet domain. The ith window coefficient p (i) is set according to the position and size of the object bounding box. For pixel locations within the bounding box, it set p (i) = 1 . For pixel locations outside the bounding box, the corresponding p (i) smoothly decays to zero as they get far from the bounding box. It compute the distances dx (i) and dy (i) to the nearest vertical and horizontal bounding box border, respectively. Then the window coefficient associated to this pixel is given by
/ \ —aw(dx(i)+dy(i)) _
p(i) = e where aw> 0 a parameter is related to the rate of decay of the window.

Representative APR 391%

Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
