Image recognitionJoint transform correlatorLarger size imageFrequency spectrum correlatorHigh-pass filteringA new method for larger size images recognition is proposed based on high-pass filtering and frequency spectrum correlation. The input images are first filtered by a high-pass filter. Then the ...

The method shown here permits the filter to be applied in a single pass, by filtering the local neighborhood four times along x and then the results filtered one time along y. Although this approach is workable and makes for a good textbook example, it is far from optimal. A more ...
Electromyography recordings were amplified (×100 for GM and TA, ×1,000 for PL; P511AC amplifiers, Grass), band-pass filtered (3 Hz to 3 kHz) and digitized with a PowerLab recording system (PowerLab16SP, ADInstruments) at 20 kHz. Data analysis The amplitude of each CMAP was ...
After analyzing the advantages and disadvantages of the theory and algorithms of IHS method and high pass filter method,this paper put forward a high pass filter method for image fusion based on IHS transformation.The algorithm first filtered the component I obtained by IHS transforming of multi-sp...
In this situation, background is estimated with a down-sampled, blurred image. To further improve vessel contrast, the data are processed using either an unsharp mask or high pass filter. In this work, data skeletonization is performed with Amira (Thermo Fisher Scientific). One of the most ...
In auditory perception, a right hemisphere (RH)/left ear advantage(LEA) for low-pass filtered stimuli and a left hemisphere (LH)/right ear advantage(REA) for high-pass filtered stimuli have been reported. Here we investigated how tonal language experience modulates this hemispheric asymmetry. We...
