2. Texture filtering - Wikipedia

   en.wikipedia.org/wiki/Texture_filtering

   Mipmapping is a standard technique used to save some of the filtering work needed during texture minification. [2] It is also highly beneficial for cache coherency - without it the memory access pattern during sampling from distant textures will exhibit extremely poor locality, adversely affecting performance even if no filtering is performed.

3. Gaussian blur - Wikipedia

   en.wikipedia.org/wiki/Gaussian_blur

   For temporal smoothing in real-time situations, one can instead use the temporal kernel referred to as the time-causal limit kernel, [8] which possesses similar properties in a time-causal situation (non-creation of new structures towards increasing scale and temporal scale covariance) as the Gaussian kernel obeys in the non-causal case. The ...

4. PPG Wave - Wikipedia

   en.wikipedia.org/wiki/PPG_Wave

   PPG Wave 2.2 front panel. PPG's Wave series represents an evolution of its predecessor by combining its digital sound engine with analog VCAs and 24db per octave VCFs, featuring 8-voice polyphony; and by replacing its nontraditional series of push buttons and sliders with a control panel consisting of an LCD and a more familiar arrangement of knobs.

5. Spatial anti-aliasing - Wikipedia

   en.wikipedia.org/wiki/Spatial_anti-aliasing

   In digital photography, optical anti-aliasing filters made of birefringent materials smooth the signal in the spatial optical domain. The anti-aliasing filter essentially blurs the image slightly in order to reduce the resolution to or below that achievable by the digital sensor (the larger the pixel pitch , the lower the achievable resolution ...

6. Kernel (image processing) - Wikipedia

   en.wikipedia.org/wiki/Kernel_(image_processing)

   In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more.This is accomplished by doing a convolution between the kernel and an image.

7. Image texture - Wikipedia

   en.wikipedia.org/wiki/Image_texture

   Artificial texture example. Natural texture example. An image texture is the small-scale structure perceived on an image, based on the spatial arrangement of color or intensities. [1] It can be quantified by a set of metrics calculated in image processing. Image texture metrics give us information about the whole image or selected regions. [1]
