Mixed reality web applications
The web application we are going to develop draws Fedora hats on top of the detected heads in a given image. In order to do this, the user uploads the image through a simple form, and then it is converted to an OpenCV matrix in memory. After conversion, a cascade classifier looking for faces is run over the matrix. A simple scale and a translation are applied to estimate the hat's position and scale. A transparent fedora image is then drawn on the specified position for each of the detected faces. The result is then returned through HTTP by giving the mixed reality picture to the user. Notice that all the processing happens on the server side, so the client is only left to upload and download the image, which is ...
