The Fourier process is normally used to identify and remove systematic noise spikes, such as regular lines that may have been introduced by a faulty image collection device. The process works as a two-way operation. First the forward transform creates a pair of intermediate raster objects that reveal abnormal data variability. After the values in those raster objects have been edited to remove the data spikes, the inverse transformation creates a raster object with the same image as the original, but with lines or other noise removed.  3, record 11, English, - Fourier%20transform

New methods of acoustic imaging are presented that provide images with reduced reverberation noise and images of nonlinear scattering and propagation parameters of the object, and estimation methods of corrections for wave front aberrations produced by spatial variations in the acoustic propagation velocity. The methods find use in a variety of applications such as acoustic imaging of geological structures, SONAR imaging of sub-sea objects, and medical ultrasound imaging. The methods are based on processing of the received signal from transmitted dual frequency band acoustic pulse complexes with overlapping high and low frequency pulses. The high frequency pulse is used for the image reconstruction and the low frequency pulse is used to manipulate the nonlinear scattering and/or propagation properties of the high frequency pulse.  3, record 12, English, - acoustic%20imaging

[A filter used] to remove random noise while preserving high frequency features (edges).  3, record 13, English, - gamma%20filter

Record number: 13, Textual support number: 1 CONT

The Gamma filter performs gamma map filtering. Gamma filtering is primarily used on radar data to remove high frequency noise(speckle) while preserving high frequency features(edges). The Gamma Map filter was first proposed by Kuan.... Lopes modified the Kuan Map filter by assuming a gamma distributed scene and setting up two thresholds. The gamma filter size ranges from 1 to 11. Different filter sizes will greatly affect the quality of processed images. If the filter is too small, the noise filtering algorithm is not effective. If the filter is too large, subtle details of the image will be lost in the filtering process. A 7x7 filter usually gives the best results.... The GAMMA filter performs spatial filtering on each individual pixel in an image using the grey level values in a square window surrounding each pixel. The dimensions of the filter must be odd, and can be from 3x3 to 11x11 pixels.  2, record 13, English, - gamma%20filter

RADARSAT ScanSAR Beam Modes : A ScanSAR beam mode is composed of either two, three, or four single beams. The sequence of beams is organized so that the data is collected from a larger area, than what can be collected using a single beam. The ability to "steer" the radar beam using different incidence angles increases the frequency of repeat coverage. For the ScanSAR beam modes, the radar backscatter decrease resulting from incidence angle differences within the image range should be considered before interpreting the image brightness of a specific target. Incidence angle corrections should be applied on the data before making a direct comparison of image brightness values from different Standard beam mode images.  2, record 18, English, - ScanSAR%20beam%20mode

Applied to image processing, this theorem states that if an image contains no spatial frequency(fc), then the original image can be reconstructed without distortion if it is sampled at a rate at least twice that of the specified frequency(2 fc).(WD, ISO 2382-30 Computer Vison, 1994).  3, record 27, English, - Nyquist%20theorem

The Culgoora radioheliograph, commissioned in 1967, was initially designed to operate at a frequency of 80 MHz. Scanning a north-south line of points across a field of view of approximately 2 E-W X 1. 6 N-S yields a two-dimensional image of the solar corona once per second.(...) Here we report the addition of a second operating frequency, 160 MHz, for the radioheliograph and work in progress to add a third frequency, 43. 25 MHz.  1, record 28, English, - radioheliograph
