How to show a pic and process it ?

Hi Sir, 

where to find the below icon in red ?

Also for the image processing, such as detect the contour of circle, line, dot, and calculate the size, which detailed function of the vision we need to use ?

I am just engaging in vision, so some basic questions, thanks for your help.

Open the Functions Palette -> Vision and Motion -> Vision Utilities -> Image Management -> IMAQ Cast Image

More generally, if you want to know where is located any VI in the Functions Palette:

 - Ctrl-H to open the Context Help;

 - Hover your subVI with the mouse and see its name displayed in the Context Help (here "IMAQ Cast Image");

 - Right-click on the diagram to open the Functions Palette;

 - In the upper-right corner, click on "Search";

 - Type the name of your VI and double-click on the result;

 - The VI is then highlighted in the palette and by going up in the menu, you can see the hierarchical path you have to go through to find the VI.

As for your second question, have a look at the Functions Palette -> Vision and Motion -> Machine Vision -> Locate Edges. There are functions for finding straight edges and circular edges in an image.
