Our aim is to implement a plant identification application that can run on smartphones, and this shared task includes it. After the plant identification task of 2013 we concluded that the most frequent trees (e. g. in Hungary) can be identified well by a leaf, when there is a white paper background behind it at the time of photographing. This is why we want to classify more accurately this kind of pictures. Our other important goal is to develop a system which can be trained online while smartphone users take more and more photos. In the previous year there was a separate shared task for the 'Sheet as Background' photos, however this year the task is very complex, and supposes solutions for hard image processing problems, not just feature extraction and classification solutions.
