In the image quantization and enhancement section, the non - linear gray mapping based on histogram specification and the enhancement digital filter in spatial domain is applied to the result digital subtraction images
對于獲得的數字剪影結果圖象採用了規定化直方圖的非線性灰度變換演算法，同時對于結果圖象的增強設計了空域數字濾波器。 -
In conventional r - d analysis, the bitrate r and distortion d are considered as function of quantization parameter q, which are usually developed in pixel - domain or spatial domain
在傳統r - d模型中，碼率r和失真d都看成量化步長的函數，而且失真評價函數一般在象素域或空域中進行。 -
We propose a color - spatial feature retrieval method based on color clustering, color clustering is introduced into color - spatial feature based retrieval method in order to decrease color quantization error, increase retrieval accuracy, and a new spatial color descriptor is proposed
2 .提出了一種採用顏色聚類的顏色-空間檢索方法。為了減小顏色量化誤差，提高檢索精度，本方法將顏色聚類引入顏色-空間檢索，提出了一種新的空間顏色描述特徵。 -
In case where long - range communication is needed, spatial diversity blind equalizer ( sdbe ) is an effective way to improve snr and suppress distortion. joint carrier phase recovery with sdbe using second order digital phase lock loop is presented to track the doppler shift, and a kind of quantization method is used to reduce the complexity of the multi - channel algorithm. its performance is very similar to the original one
模擬結果表明，採用二階數字鎖相環的空間分集均衡演算法的跟蹤性能超過了採用一階鎖相環和未加鎖相環的演算法，可有效補償由於水聲通道時變而引入的載波相位快速變化；採用誤差量化的演算法和原演算法的收斂和踉蹤性能都很接近。
