Description: Gaussian filtering in one, two or three dimensions is among
the most commonly needed tasks in signal and image processing.
Finite impulse response filters in the time domain
with Gaussian masks are easy to implement in either floating
or fixed point arithmetic, because Gaussian kernels are
strictly positive and bounded. But these implementations are
slow for large images or kernels. With the recursive IIRfilters
and FFT-based methods, there are at least two alternative
methods to perform Gaussian filtering in a faster way,
but so far they are only applicable when floating-point hardware
is available. In this paper, a fixed-point implementation
of recursive Gaussian filtering is discussed and applied
to isotropic and anisotropic image filtering by making use of
a non-orthogonal separation scheme of the Gaussian filter. Platform: |

Description: Image Edge Enhancing Coherence Filter Toolbox，各向异性非线性扩散滤波器-This toolbox will perform Anisotropic Non-Linear Diffusion filtering on a 2D gray/color or 3D image. This filtering will reduce the image noise while preserving the region edges, and also enhancing the edges by smoothing along them.
This is one of the more advanced image enhancement methods available, and also contains HDCS from october 2009. The result looks like an artist painted the image, with clear brush strokes along the image edges and ridges, see screen-shot.

-In order to suppress noise, as far as possible to keep the image edge information, an adaptive anisotropic Gaussian filter design methods. The method by the independent strength spread (IDS) model determines the long axis of the filter scale, the pixel neighborhood smoothness determine the ratio of minor axis, and then there' s gray gradient direction of adaptive decision the long axis of anisotropic filter. Simulation results show that the proposed adaptive anisotropic filter has a strong noise suppression and preserve edges. Platform: |

Description: 利用OpenGL實作shadow map，程式碼可以直接執行。
1.利用鍵盤方向十字鍵可以控制光的位置。
2.F1鍵可以決定是用mipmap還是anisotropic filter。
3.滑鼠的中間滾輪點擊一下，可以使camera自動旋轉，再按一下就停止轉動。
4.PageDown降低camera的高度，PageUp則是增加camera的高度。-OpenGL implementation shadow map, the code can be executed directly. 1 use the keyboard direction the Arrows can control the position of the light. 2.F1 key is supplied mipmap or anisotropic filter can decide. The middle mouse wheel click, you can make the camera automatically rotates, and click stop turning. 4.PageDown reduce the height of the camera, PageUp is to increase the height of the camera.
