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: 小数在计算机内有两种表现形式定点数和浮点数。在定点机中，由于小数点的位置固定不变，以此当机器处理的数不是纯小数或纯整数的时候，必须乘上一个比例因子，否则会产生“溢出”。而实际上计算机处理的数不一定是纯小数或纯整数，而且有些数据的数值范围相差很大，不能直接用定点小数或定点整数表示，必须用浮点数来表示。浮点数的表示精度要比定点数高的多。要求用定点运算来仿真浮点运算，用定点数运算的思想去实现浮点数的运算。-Decimals in the computer, there are two manifestations of fixed-point and floating-point numbers. In the fixed-point machine, because of the location of the decimal point is fixed, as when dealing with a number of machines is not pure decimal or pure integer, the ratio must be multiplied by a factor, otherwise will have a spillover. In fact a number of computer processing is not necessarily the pure decimal or pure integer, and some of the numerical range of data varied widely, not directly with fixed-point or fixed-point decimal integer that must be expressed in floating-point numbers. Floating-point precision than that of fixed-point higher. Asked to use fixed-point calculations to simulate floating-point operations with fixed-point computation to realize the idea of floating point arithmetic. Platform: |
