Opencv experiences (1)
The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing;
Knowledge
Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value.
Idea: Compare the minimum data selected each ti
Summary:Ordinary BST does not guarantee a good performance after multiple operations. So we need a BST, yes. The cost of each insertion and search is a logarithmic function of the large size of the tree. The 2-3-4 tree is a kind of BST that maintains balance.2-3-

Scenario: Resolve a lookup in a large amount of data on the hard disk. Because a large amount of data is stored in the hard disk, can not be loaded into memory all at once, and each time a data read the hard disk, reading speed is too slow, it is necessary to use a part of a data structure read in, this is the role of multi-path search tree. 2-3 Trees

Common ratios
At the beginning of the information age of 195x, the most notable feature is that analog technology has turned to digital technology, graphic design has been gradually led by electronic devices from paper to media, and the granularity units have changed, but this is not so much for designers, the problem is the ratio.
Aspect ratio, which is the height ratio, only discusses the three most common categories: photography, video, and display equipment.
