作为对比,linear filtering模式会 混合两个或者多个像素来得到最终采样出来的颜色。在linear filtering模式下使用的linear filtering方法就是简单的线性插值-就如它的名字所提示的那样。在很多情况下,这样的过滤方式已经足够产生高质量的画面了并且 这些过滤方式是被硬件所直接支持的。然而,当我们放大图片的时候,我们可能会...

In3D computer graphics,anisotropic filtering(abbreviatedAF) is a method of enhancing the image quality oftextureson surfaces of computer graphics that are atoblique viewing angleswith respect to the camera where the projection of the texture (not the polygon or other primitive on which it is render...
Thus, in this work, Laws' mask analysis has been used for feature extraction by filtering an image with different special 2D masks to compute different texture descriptors that prove to be useful in texture analysis. The basic kernels used in the formation of 2D masks are Level (L), Edge ...
Entropy in images has had different applications, such as segmentation, filtering, and obtaining specific information. The entropy filter replaces the intensity of pixels by entropy values, in whose process Shannon’s Entropy algorithm is applied, where it is required a structured element with a cer...
Filteringapproaches, which convolve an image with a bank of filters followed by some nonlinearity. One pioneering approach was that of Laws (1980), where a bank of separable filters was applied, with subsequent filtering methods including Gabor filters (Bovik et al.1990; Jain and Farrokhnia1991;...
If filtering is specified,Device.StretchRectanglefails unless the driver setsCaps.StretchRectangleFilterCaps. IfTextureFilter.Noneis specified, the driver chooses a filtering algorithm. The stretch operation supports color-space conversion from YUV to high-precision RGBA only. Stretching between rectangles ...
Reduce your Unity build filesize and improve GPU rendering with Unity texture compression! How to use mipmapping and anisotropic filtering to optimize performance and improve unity texture quality. Fix POT texture error 'Only POT textures can be compress
For example, I can use: a mipmapping or anisotropic filtering to eliminate the texture map aliasing, a FXAA to eliminate the light accumulation buffer aliasing and finally a MSAA to eliminate the geometry aliasing. ps: I used the nanosuit model from this site: www.gfx-3d-model.com/2009/...
Rather than collecting a new image dataset from scratch, our starting point is the excellentopen surfaces(OS) dataset that was recently introduced by Bell et al. (2013). OS comprises 25,357 images, each containing a number of high-quality texture/material segments. Many of these segments are...
