The testing results illustrate that the proposed algorithm has a certain improvement in recognition accuracy and effectively avoids the problem of large amount of computation and long time in iris matching because of the variety and quantity of iris database. Key words : iris recognition;K-means ...
I have a series of data and using the custom equation, I could fit the data on the theoritical equation. I would like to see the graph and fit curve in log scale but I don't know I to change the x values in log scale. Coyuld you please let me know how to do it? Haev a ...
MATLAB图像的sobel算子处理 下面简单介绍一下有关sobel算子去处理二值化图像的原理: 1、打开MATLAB软件,在其主界面的编辑器中写入下列代码: I=imread('G:\MATLAB\bm.bmp'); %读取当前路径下的图片 subplot(2,2,1),imshow(I); title('原始图像... ...
Log Plot Using thesemilogy()Function in MATLAB If you want to plot the variables on the y-axis of base 10 log scale and x-axis of linear scale. You can use thesemilogy()function. See the below code. a=1:100;b=2*a;lg=semilogy(a,b)grid on axis tight ...
Common logarithm (base 10) collapse all in page Syntax Y = log10(X) Description Y = log10(X)returns the common logarithm of each element in arrayX. The function accepts both real and complex inputs. For real values ofXin the interval (0,Inf),log10returns real values in the interval ...
This is how our input and output will look like in the Matlab command window: Input: Output: As we can see in the output, we have the log of 4 to the base “e” as 1.3863, which is the same as expected by us. Example #2 ...
