The frequency domain plays an important role in image processing to smooth, enhance, and detect edges of images. Although image data typically does not include imaginary values, the fast Fourier Transform (FFT) has been used for obtaining spectra. In this paper, the fast Hartley Transform (FHT) is used to Transform two-dimensional image data. Because the Hartley Transform is real valued, it does not require complex operations. Both spectra and autocorrelations of two-dimensional ultrasound images of normal and abnormal livers were computed.

An important book that cover wavelet domain. It help a lot in understanding wavelets and their applications. Beside explanations of the Transform and application of this, there are also presents the reasons why wavelets are better than Fourier Transform.

Abstract - A fl exible multiscale and directional representation for images is proposed. The scheme combines directional fi lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional fi lter banks provide an effective method to implement the digital curvelet Transform. The regularity issue of the iterated fi lters in the directional fi lter bank is examined.

Main program running when workpiece is ready on deferent belt(deferent_ready=ture). * Call Square_Wave subroutine to generate 0.5ms square wave on P1.2 to drive * electromotor,then drive deferent belt step forward. When it steps to the measure * zone, it stops to be measured. Then call A_D subroutine to Transform analog * signals to digital signals , after then call serial subroutine to transfer * digital signals to PC. Call square wave subroutine to drive deferent belt step to * original position waitting for defere ready flag to run the next circle.
