VIDEO SHOT BOUNDARY DETECTION(10)

In this work, we used the extraction of key frames method based on detecting a significant change in the activity of motion. To jump 2 images which do not distort the calculations but we can minimize the execution time. First we extract the motion vectors between image i and image i+2 then calculates the intensity of motion, we repeat this process until reaching the last frame of the video and comparing the difference between the intensities of successive motion to a specified threshold.

The idea can be visualised in figure below.

Video shot boundary detection using Independent component analysis

A new method for shot boundary detection using independent component analysis (ICA) is presented. By projecting video frames from illumination-invariant raw feature space into low dimensional ICA subspace, each video frame is represented by a two-dimensional compact feature vector. An iterative clustering algorithm based on adaptive thresholding is developed to detect cuts and gradual transitions simultaneously in ICA subspace. This method has the following major steps: (i) Raw feature generation from illumination-invariant chromaticity histograms; (ii) ICA feature extraction; (iii) Dynamic clustering for shot detection.

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.
