How to do manual thresholding using the set of images?

 Hi,

I have a code for the Manual thresholding and I am unable to run the code correctly. I am using two images to do the thresholding. The imorig is the below original image
 
and the im is the below segmented image. I want to do thresholding with the help of two images.
 
this is how i run the code:
 
 >> im=imread('5013lt685dapi_segmented.tif');
 >> imorig=imread('5013lt685dapi.tif');
>> name='abc';
>> manual_thresh(im,name,imorig);

AND THE ERROR I AM FACING IS

 Error using set
Bad property value found.
Object Name: image
Property Name: 'AlphaData'.

 Error in manual_thresh>update_plot (line 239)
 set(h_ax1, 'AlphaData', bw);

 Error in manual_thresh (line 180)
 update_plot

If you put a breakpoint at line 239

 

 set(h_ax1, 'AlphaData', bw);

you will observe that bw will have the same dimensions as your input image. So if the input image is mxnx3, then bw will be mxnx3 as well.

In order to use nonscalar alpha data, you need to specify the alpha data as an array equal in size to CData of images and surfaces or…
 
Since CData is your original image, your bw has the correct size in width and height (mxn). What is not all that clear from the notes but probably should be based on the context is that your AlphaData should be mxnx1. Your line of code then becomes

What are some good alternatives to Simulink?

Get MATLAB projects with source code for your learning and research. SIMULINK is a visual programing environment specially for time transient simulations and ordinary differential equations. Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model right in the GUI and with

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.
