Mobile App for My Work

I am Dr. Bratati Das working as a postdoctoral researcher at IIS, University of Tokyo.

We have a polymer that changes its color from blue to red when a pressure is applied by e.g. scratch. Our goal is to make a package that visualizes the damages during the transportation and a corresponding mobile app, where users can take a photo of the red scratches on the package and convert the red intensity into the applied pressure values. Below we explain these steps.

1. Users scan the red scratch by taking a photo with a mobile.

2. The app separates the photo into R, G, B images.

3. The app only uses R channel (discard the rest). The app detects the starched line from the R channel image and extract the average value of the red intensity on the scratched line. The app also detects the red intensity on the background. The app calculates Rstratch – Rbackground = dR.

4. We have a calibration equation (Pressure = dR x alpha). Based on the calibration equation, the app converts the average red intensity to the average pressure.

5. The app displays the estimated average pressure on the screen.

Note

In reality, each mobile phone has different cameras, light condition etc. Therefore, an identical scratch can yield different red intensity values in each time. To overcome this issue, we need to do an additional calibration against each camera. However, this could be a future project…

Your creativity in this project can be pivotal. Please showcase your previous relevant work when bidding.
