Compression of images

In most cases all these operations are computed with analysis in the frequency space (Pratt 2001). This subject is frequently skipped because of the difficulties in math formulas or in math in general. But spatial domain and frequency domain are linked, and every operation that can be made in spatial domain with an augmented difficulty and with more computational resources can be made easily in the frequency domain. The word filter comes from the frequency world and is one of the common operations done in image or signal analysis. One of the common operations done in the frequency domain is the compression of images this aspect has lately returned to the footlight thanks to the need of radio-... [Pg.61]

Figure 10 An STM image of a hydrogen plasma annealed (001) CVD diamond surface. Two types of antiphase boundaries are labeled API and AP2. The 3X1 configurations are marked L. The distance between dimer rows is 5 A. The compression of images is caused by instrumental calibration. (From... Figure 10 An STM image of a hydrogen plasma annealed (001) CVD diamond surface.
