PrefaceDigital image processing is a popular, rapidly growing area of electrical and computer engineering. Digital image processing has enabled various intelligent applications such as face recognition, signature recognition, iris recognition, forensics, automobile detection, and military vision applications. Its growth is leveraged by technological innovations in the fields of computer processing, digital imaging, and mass storage devices. Traditional analog imaging applications are now switching to digital systems to utilize their usability and affordability. Important examples include photography, medicine, video production, remote sensing, and security monitoring. These sources produce a huge volume of digital image data every day. Theoretically, image processing can be considered as the processing of a two-dimensional image using a digital computer. The outcome of image processing could be an image, a set of features, or characteristics related to the image. Most image processing methods treat an image as a two-dimensional signal and implement standard signal processing techniques.Many image processing techniques were of only academic interest because of their computational complexity. However, recent advances in processing and memory technology made image processing a vital and cost-effective technology in a host of applications. Multi-scale image transformations, such as Fourier transform, wavelet transform, complex wavelet transform, quaternion wavelet transform, ridgelet transform, contourlet transform, curvelet transform, and shearlet transform, play an extreme...
