Aim
Read value from an analogue temperature indicator.
Input
Set of images with thermometer showing different temperature values.
Output
Value of indication showed by indicator.
Hints
The analogue indicator have theirs best times behind. But there are some applications where replacing these indicator can be expensive. This example shows how to obtain the value from a such kind of analogue indicators.
In this case hand of the meter can be easily found using 1D Edge Detection technique. To do that scanning should be performed on a circular scanning path.
