Signal Reconstruction Techniques Applied to High Frame Rate Sequences

Reconstruction of high frame rate image sequences in biomechanical related areas

“…In order to evaluate and measure the sequence reconstruction quality, two parameters were analysed for all the reconstructed signals: the RMSE (Root Mean-Squared Error) and the PSNR (Peak Signal to Noise Ratio [8] [9]). The equations used to calculate these two parameters are described in [4].…”

“…The main objective is to analyze the nature of each signal and then to apply a decimation process which still guarantees that reconstruction is possible, with an acceptable tolerance or error. In this first stage and to test the chosen algorithm, a linear decimation was applied to all the signals [4].…”

“…The first results published in [4] show the results of the signal reconstruction without using a coding method, so new tests were done now using different codification methods in the chosen sequence. The proposed methodology is presented in Fig.…”

“…The underlying idea is to propose a new compression methodology that will take advantage of the high temporal correlation in high frame rate sequences using both compression and reconstruction techniques. Work related on [4] shows the first results in the regular decimation of these sequences and the usage of signal reconstruction algorithms to recover the original data.…”
