[Mechatronic]

I am a student..Then, currently I am learning how to use Labview in Image acquisition for my project..My project is to snap an image and save it in jpeg format. Then, rectangle a part of the picture to learn the template and search the template in the picture..For now, my problem is after snap the image, I rectangle a part and try to learn the template..But, there is an error shown which is the template is too small...Therefore, I cannot learn the template to preceed to the search process..So, can anyone help me to solve this problem..It is urgent and I hope someone can help me solve this problem..Besides, I have attached my program and hope someone can help me solve my program..Thank you..

Hi Mechatronic,

In order for pattern matching to work, there must be sufficient information in the template (edge/intensity information) so the template size cannot be too small.

I've looked through your VI and I believe you are using a webcam? What is the image you are trying to capture, and what is the size of the template you are currently using?

In software, if possible select a larger template area. Otherwise in hardware, try zooming in nearer to your object of interest, or use a higher resolution webcam.
