CROPPING TECHNIQUES AND RESULT COMPARISON: EVALUATION(3)

To understand deeply, we would like to give an example here. Suppose we are evaluating one of the representative set called “I3-75”. As we mentioned earlier that we consider 20 images in a representative set, first we ask to rate 10 top ranked images generated from ranking mechanism and then we show 15 top ranked images and ask participants whether they think that these 15 images are more or less representative then 10 images. If they say yes, then we ask for the rating again otherwise we directly show whole 20 images summary and asking the same question in perspective of 10 and 15 images summary. Again if they say “yes”, then we ask again rating for the 20 images summary. The pattern of the questionnaire will be same for rest of the five result sets.

Figure 7 : Time consumed by different cropped window

From the above graph, there is nominal difference in the time taken by windows generating algorithm (blue bar) for N=3 and N=5.The time taken by clustering algorithm is higher for both N=5, C=85% random and sequence windows. The reason of this is to fetch sift descriptors of all the windows and then process for the clustering. While for the set N=3, C=66% sequence took very less time. There is no much difference in time taken by the ranking mechanism for all sets. The set N=5, C=75% sequence windows took long time for the ranking mechanism in compare to others. Maximum total time is consumed by N=5, C=85% random windows set. The time taken by clustering and fetching centroids increases with the increase of number of windows N and the coverage C.

Representative APR 391%. Average APR for this type of loans is 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.
