When i run my simulink model, the scope gives me correct graph but it disapears. It only the time 9-10 is shown on plot. Can anyone help to represent the graph.
Thanks
By default, only the last 5000 data points are plotted on the scope. You almost certainly have 50000 simulation steps from 0-10s and hence are only seeing the 5000 points from 9-10s.
Use the zoom controls on the scope to view all the points after simulation, or change the scope properties to change how they appear during simulation. How to do that is different in different versions of Simulink, but should be relatively easy for you to find.

I would like to use the Autonomous Driving Toolbox in Matlab. But I prefer to know more abou it before I buy it. For instance, is it possible to customize some modules in the toolbox with some different algorithms than the default? For example, in the motion planning section of the toolbox, there's only one planner module provided by Matlab called "pathPlannerRRT" which implements the RRT algorithm for path planning, is it possible to create another customized planner with another or self-designed algorithm?

Basically I need to extract the identification number of marathon runners from the image. Till now I was able to get the bib part alone from the whole image. Now I need to extract the numbers from that image:
I need to extract 1430 from the image. I have tried some methods like OCR and blob detection techniques but they are not successfull for all images.
Have you tried using Stroke Width Transform (SWT)? You can find a Matlab implementation of the first stages of SWT here.
Take a look at this example in the Computer Vision System Toolbox.

Ive been researched Information Visualization techniques application to image collections. I need some image datasets with features. Ideally, would be good find a dataset in a file representing each image attributes value,like this https://archive.ics.uci.edu/ml/datasets/Corel+Image+Features so I could project on my software, but it has been too hard to find, so I am trying to work with matlab algorithms to extract the features. So, I want some datasets.
Here you can find the ImageCLEF 2013 dataset with different features: GIST, Color Histograms, SIFT, C-SIFT, RGB-SIFT and OPPONENT-SIFT.

My Simulink model:
Is it possible to print this graph without scope (in matlab code)?
Yes, you can save the data to the workspace using a To Workspace block and plot it after the simulation has finished using standard MATLAB code. Plenty more options in the doc under Visualize Results.
Rightklick on a Signal->Create connected viewer->Floating scope.
If you need more advanced techniques, check the documentation examples about signal logging and signal inspection.

I have tried manual detection using LS polynomial fitting here. But that cannot be used in my project as mine has to be a fully automated system.
Take a look at the Scale-Invariant Feature Transform, or SIFT. This video explains it well. You "train" a detector with one or more images of eyelids, and the detector locates similar regions in the input images. It's the de facto general purpose feature detector - although more specialized tools like face detectors are faster.
The "Scale-Invariant" part means that it can detect the same object at different sizes and rotations.
