In the applications of wavelets, the vlsi design has been highly required. the coefficients in the integer wavelet transform are integer, so that the perfect reconstruction and lossless compression is possible
整數小波變換由於其小波系數為整數，逆變換可完美恢復小波變換前的數據，因此在無損圖像壓縮等領域有著重要應用。 -
When calculate the correlation function of binary array pairs, using the boolean calculation instead of the decimal multiplication, using the method of count the number of 1 in binary integer to calculate the correlation function of binary array pairs, the speed of searching is obviously improved by these methods. by the algorithm introduced in this paper, the constant weight and normative perfect binary array pairs whose volume from 4 to 28 and quasi - perfect binary array pairs whose volume from 2 to 24 were searched and gi ved the new result
此外，採用二進制整數來表示陣列，通過對整數的邏輯運算來實現陣列偶的移位變換、完全采樣變換等運算；在計算二進陣列偶的相關函數時，用整數的邏輯運算代替十進制中的乘法運算，並用計算二進制整數中1的個數的方法來計算二進陣列偶的相關函數，以上方法的採用明顯地提高了搜索速度。利用上述演算法，對體積為4 28的等重規范型最佳二進陣列偶和體積為2 24的準最佳二進陣列偶進行了搜索，並給出了新的結果。 -
Using the idea of secret - sharing and signature - of - knowledge, a new perfect and strong key - insulated signature scheme based on the assumption of integer factorization problem is proposed. the scheme has a low computation in key updating and signing, thus fitting for the mobile devices
