In my app, there is a functionality of detection documents (like a Scanbot app) and then prospect it to document. So, far I am able to detect documents with single colour or documents which are clearly distinguishable from background. But the problem arises when the document is of multi-color. To clearly understand the problem , I have attached an image: I am new to OpenCv with Android.I am trying to make an application which auto detects documents using OpenCv - 2.4.13 .

To clearly understand the problem , I have attached an image: enter image description here As you can see, the blue line is a detection line and it is not detecting full document. What i did so far is as below : After some research, I came to know that the problem rely on canny edge detection. Below is the result I get after canny edge detection: Is there any way to achieve this? Any help will be highly appreciated !! Thanks in advance |
