how Compute the log10 of the image in matlab and what mean log10 of image? and image is graylevel. for example: a=imread('image.jpg'); im2bw(a,log10); i want know the log10 how to effect on image?

I'm trying to read a serial device that MATLAB employs various optimizations to minimize this kind of kernel launch proliferation. However you may find you get better performance when you explicitly identify parts of your code that you know could be compiled into a single kernel. To do this, write the kernel in the MATLAB language as a function, and call it using the wrapper arrayfun. Because log10() is a static method of Math, you always use it as Math.log10(), rather than as a method of a Math object you created (Math is not a constructor). This function is the equivalent of Math.log(x) / Math.log(10). For log10(e) use the constant Math.LOG10E which is 1 / Math.LN10.

Let's use the cameraman.tif image provided by matlab.. Img = imread ('cameraman.tif'); This image is a uint8 image (i.e.

Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf). For complex and negative real values of X, the log10 function returns complex values.
