代码说明:

  mbedded Zerotrees of Wavelet transforms (EZW) is a lossy image compression algorithm. At low bit rates, i.e. high compression ratios, most of the coefficients produced by a subband transform (such as the wavelet transform) will be zero, or very close to zero. This occurs because "real world" images tend to contain mostly low frequency information (highly correlated). The locations where high frequency information does occur (such as edges in the image) this is particularly important in terms of human perception of the image quality, and thus must be represented accurately in any high quality coding scheme.

    .已知某炉温控制系统,要求温度保持在600℃恒定,针对该控制系统有以下控制经验: (1)若炉温低于600℃,则升压,低的越多升压越高; (2)若炉温高于600℃,则降压,高得越多降压越低; (3)若炉温等于600℃,则保持电压不变。 设模糊控制器为一维控制器,输入语言变量为误差,输出为控制电压。输入输出变量的量化等级为7级,取5个模糊集,试设计隶属度函数误差变化划分表,控制电压变化划分表和模糊控制规则表。 (Known for a temperature control system that requires a constant temperature is maintained at 600 ℃, the following control experience for the control system: (1) If the furnace temperature is below 600 ℃, the step-up, the more the higher the lower the boost (2) if the furnace temperature is higher than 600 ℃, the blood pressure, high blood pressure, the lower the more (3) If the furnace temperature is equal to 600 ℃, then keep the voltage constant. Set of fuzzy controller for one-dimensional controller, input linguistic variables for error, the output control voltage. Input and output variables of quantization levels for seven, take five fuzzy sets, membership function test design error variance divided table, partition table and the control voltage variation fuzzy control rule table.)
