“…One significant advantage of using the DWT approach for signal processing is to design high and low pass filters as digital filters on programmable logic devices, such as modern FPGAs. This enables the algorithms implementation directly in hardware, which leads to the high performance needed in real time signal processing applications [13][14][15] and ultimately to embedded monitoring systems.…”

“…DWT has an advantage of being easy to use. It also, provides flexible multi-resolution analysis of an image [19][20][21]. DWT used in signal and image processing in order to obtain the useful information from the signal or image that can be used for feature extraction stage.…”

“…In this study, a novel implementation of DWT and PCA is considered. DWT, see for example [19][20][21], is normally used in signal and image processing in order to obtain the useful information from the signal or image that can be used for feature extraction stage. The Principal Component Analysis (PCA) is widely used in image processing, particularly in the area of face recognition and compression [22][23][24][25].…”
