This paper proposed a new symmetric image encryption method using the concepts of Deoxyribonucleic Acid (DNA) sequence and Binary Search Tree (BST). The method initiates by generating the secret key. Next, the number of nodes in candidate BST is determined deterministically prior to create the ...
image.png 二叉树具有天然的递归结构。 1.每个节点的"左子树"也是一棵二叉树,每个节点的"右子树"也是一棵二叉树。 二叉树不一定是"满的",即,某些节点可能只有一个子节点;更极端一点,整棵二叉树可以仅有一个节点;在极端一点,整棵二叉树可以一个节点都没有; 实现二分搜索树 二分搜索树的构造函数、getSize方...

binary image [′bīn·ə·rē ′im·ij] (computer science) A representation in a computer storage device of each of the holes in a punch card or paper tape (for example, by indicating the places where there are holes with a 1 and the places where there are no holes with a 0), to...

Binary search of the value 7 in an array. The image by AlwaysAngry is distributed under CC BY-SA 4.0 license. Now assume that we know two indices L<R such that AL≤k≤AR . Because the array is sorted, we can deduce that k either occurs...

The selection of bits is driven by a geometrically motivated algorithm, which, in effect, removes nodes with only one child from the tree. The performance of ComBI is compared with MIH. It reaches a precision of 0.90 on ∼80M tiny image data set and SIFT-1B data set in a much lesser...
