  • Band-pass filter — A band pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band pass filter is an RLC circuit (a resistor–inductor–capacitor circuit) …   Wikipedia

  • Homomorphic filtering — is a generalized technique for signal and image processing, involving a nonlinear mapping to a different domain in which linear filter techniques are applied, followed by mapping back to the original domain. This concept was developed in the… …   Wikipedia

  • Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… …   Wikipedia

  • Edge preserving smoothing — is an image processing technique where the edge information is preserved during the smoothing process. It uses non linear operator which is able to remove texture and noise, while keeping edges and corners. The technique is known also as edge and …   Wikipedia

  • Acutance — An image with artificially increased accutance Another illustration, where overshoot caused by using unsharp masking to sharpen the image (bottom half) increases acutance. In photogra …   Wikipedia
