example, when we look for a boundary that is a straight line. Do you use all the dots in the line to represent the line? No, we just need the two ends of the line. This is CV2. Chain_approx_simple to do. It removes the redundant points on the contour, compresses the contours, and saves memory overhead. We use the rectangle in the to demonstrate this technique. Draws a blue circle on each coordinate in the contour list. The first figure shows the use of CV2. The effect of Chain_approx_none, alto
An embedded multiplier can be configured as an 18 × 18 multiplier or two 9 × 9 multiplier. For multiplication operations greater than 18 × 18, Quartus II software cascade multiple embedded multiplier modules. Although there is no limit on the Data Bit Width of the multiplier, the larger the data bit width, the slower the multiplication operation.
In addition to the embedded multiplier in the cyclone IV device, you can use the m9k memory module as the

Summary: Credit scoring card model is a mature forecasting method in foreign countries, especially in the field of credit risk assessment and financial risk control, which is a generalized linear model of two classified variables, which is based on the discretization of model variable woe coding mode. This paper focuses on the model variable woe and IV principles, in order to express the convenience of the model target scalar 1 as a default user, for
Basic concepts of JavaScript (iv) --- operators and javascript OperatorsOperator 1. unary operator
The operator that can operate only one value is called The unary operator. The unary operator includes the increment (decrement) operator and the unary plus (decrement) operator.
The increment/decrease operator is divided into the increment/decrease operator and the increment/decrease operator. The increment/decrease operator is used in the same way as t
[CCID news] Sun Microsystems announced the upcoming release of ultrasparc iv + chip. The IV + chip-based server runs twice as fast as the ultrasparc IV server. The new chip, codenamed "Panther", will detail details about the high-end processor on Tuesday.
Like the current ultrasparc IV chip, ultrasparc

First of all, we need to determine whether there is a collinearity between variables, if there is a high degree of correlation, just save the most stable, the highest predictive power. It needs to be tested by VIF (variance inflation factor), which is the variance expansion factor.Variables are divided into continuous variables and classification variables. In the scoring

Because I use the four-generation development board of the black gold industry and the central chip uses the cycloneiv e of Altera, read the information on the device's official website and take notes for future reference. The cyclone IV device family has the following features:■ Low-cost, low-power FPGA Architecture:■ 6 K to 150 K logical units■ Up to 6.3 MB of Embedded Memory■ Up to 360 18 × 18 multiplier for DSP processing-intensive applications■
