Pascal VOC Data Set Analysis Pascal VOC provides a set of standardized and excellent datasets for image recognition and classification, and an image recognition challenge is held every year from 2005 to 2012. This paper mainly analyzes the content of Pascal VOC data set and object recognition in image. Here we use Pascal VOC2012 as an example. Download Address: C

a null reference must contain the same number of black nodes.(3) Bottom-up insert: 1. The parent of the newly inserted item is black, the insert completes2. If the parent node of the insertion node is red:2.1 The sibling node of the parent node is black and can be rotated either by single or double.2.2 The sibling of the parent node is also red and needs to be resolved by taking action.(4) Top-down red-black tree: You can advance the red and black tr

Mysql interaction protocol analysis-mysql package basic data, mysql package basic format, mysql Interaction Mysql interaction protocol is a common protocol used to develop mysql peripheral components, such as JDBC and libmysql. Here we need to realize that the mysql interaction protocol is actually a half-duplex interaction protocol. As for why, we need to dig a small hole and fill it out later. Before disc

You can refer to this article below http://www.jb51.net/article/6488.htm SQL: $SQL = "Delete from ' doing ' where ID in (' 1,2,3,4 ')"; Data is separated by commas. Form: Copy the Code code as follows: 　　 Good $id_dele=$_post[' Id_dele ' will be an array, although PHP is a weak type, but there is no ASP weak. ASP can directly: Sql= "Delete from [doing] where ID in ('" ID_Dele ') "is deleted. But PHP can't put $id_dele directly in. Because $id_dele i

In the Sorting Algorithm, there are three types of simple sorting algorithms: Bubble sorting, select sorting, and insert sorting. learning and understanding these three sorting algorithms helps to further study the data structure and algorithm analysis. Next, let's briefly talk about the principles and differences of Bubble sorting, selection sorting, and insertion sorting. Bubble sorting principle:1. Comp

one-dimensional array in column form5. Row-StackedSplitting numpy arraysRelated functions Hsplit (), Vsplit (), Dsplit (), and split (). We can either divide the array into an array of the same shape, or we can begin to cut the array from the specified position.1. Split horizontallyThe split () function equivalent to calling the parameter Axis=1:2. Split verticallyWhen the parameter Axis=0,split () function also decomposes the array along the vertical axis3. Deep splitThe premise is that there
