This project was done as a part of the Identify Characers From Product Images competition. The competition was hosted in CrowdAnalytix.

Data (Provided by CrowdAnalytix)

The data consisted of product images like t-shirts, bags, keychains, mobile covers, etc. with characters graphics.

Training Set: 6694 images across 42 categories Test Set: 3727 images

The data had label inconsistency of 2-3%. Had to manually resolve the label inconsitency.

Additional Data

As the data provided by CrowdAnalytix was not equally distributed across the 42. Some categories had fewer data comparatively to the other categories. To resolve this data insufficiency among the categories we downloaded the additional data with the help of gi2ds  and this tutorial created by Andrian Rosebrook .

You can download the data from here (Comprises the data provided by CrowdAnalyticsX and the above mentioned additional data). The filenames of images from Crowdanalytix starts with Cax_train and the other images filenames start with number.
