  • Lecture 11 : Discrete Cosine Transform Moving Into the Frequency Domain
    Lecture 11 : Discrete Cosine Transform Moving into the Frequency Domain Frequency domains can be obtained through the transformation from one (time or spatial) domain to the other (frequency) via Fourier Transform (FT) (see Lecture 3) — MPEG Audio. Discrete Cosine Transform (DCT) (new ) — Heart of JPEG and MPEG Video, MPEG Audio. Note : We mention some image (and video) examples in this section with DCT (in particular) but also the FT is commonly applied to filter multimedia data. External Link: MIT OCW 8.03 Lecture 11 Fourier Analysis Video Recap: Fourier Transform The tool which converts a spatial (real space) description of audio/image data into one in terms of its frequency components is called the Fourier transform. The new version is usually referred to as the Fourier space description of the data. We then essentially process the data: E.g . for filtering basically this means attenuating or setting certain frequencies to zero We then need to convert data back to real audio/imagery to use in our applications. The corresponding inverse transformation which turns a Fourier space description back into a real space one is called the inverse Fourier transform. What do Frequencies Mean in an Image? Large values at high frequency components mean the data is changing rapidly on a short distance scale. E.g .: a page of small font text, brick wall, vegetation. Large low frequency components then the large scale features of the picture are more important. E.g . a single fairly simple object which occupies most of the image. The Road to Compression How do we achieve compression? Low pass filter — ignore high frequency noise components Only store lower frequency components High pass filter — spot gradual changes If changes are too low/slow — eye does not respond so ignore? Low Pass Image Compression Example MATLAB demo, dctdemo.m, (uses DCT) to Load an image Low pass filter in frequency (DCT) space Tune compression via a single slider value n to select coefficients Inverse DCT, subtract input and filtered image to see compression artefacts.

  • Signal Shorts
    Signal Shorts Bill Fawcett Director of Engineering The Problem WMRA has published a coverage map which shows where we expect our signal to reach, based on formulas devised by the FCC. Yet even within our established coverage area, there are locales in which the signal sounds "fuzzy". In most cases, the topography of the area is causing "multi-path" interference, that is, reflections of the signal off of nearby mountains adds to the direct signal, but delayed somewhat in time, and scrambles the received signal. This is the same phenomenon that causes "ghosts" on your TV (shadow- images on your screen, not the "X-Files"). Multipath is a significant problem along the I-81 corridor North of Harrisonburg to Strasburg. Also at Penn Laird along Route 33. Multipath problems are so site-specific that moving a radio a few feet may make a difference. The next time you get a fuzzy signal at a traffic light you may note that it clears up by advancing a few feet (watch out for the car in front of you, or you may have other, more serious, problems). Switching to mono, if possible, will also help. Other areas suffer from terrain obstructions. This may be noted at Massanutten Resort, and in the UVA area of Charlottesville. For those outside of the predicted coverage area, signal strength (the lack of) may be a problem, as may interference. North of Charlottesville this is a big problem, with interference from a high-power station in Washington D.C. causing problems. Lastly, the downtown Charlottesville area suffers from interference from WCYK's 105.1 translator.
