The IIIT-Synthetic-R-Gujarati dataset consists of synthetically created 6,12,300 word images along with their corresponding annotations. To create synthetic images, freely available Unicode fonts are used to render synthetic word images. The number of fonts used for Gujarati is 807. We use ImageMagick, Pango, and Cairo tools to render text onto images. To mimic the typical document images, we generate images whose background is always lighter (higher intensity) than the foreground. Each word is rendered as an image using a random font. Font size, font styling such as bold and italic, foreground and background intensities, kerning, and skew are varied for each image to generate a diverse set of samples. A random one-fourth of the images are smoothed using a Gaussian filter with a standard deviation (𝜎) of 0.5. Finally, all the images are resized to a height of 32 while keeping the original aspect ratio. This dataset is divided into Training, Validation, and Test Sets consisting of 4,28,610, 61,230, and 1,22,460 word images and their corresponding ground truth transcriptions. There are 3,60,026 Gujarati words in the training set.

Training Set:

train.zip contains folder named “images” with 4,28,610 word level images, “train_gt.txt” containing image name and ground truth text separated by “Tab space” and “list_of_words.txt” contains list of 3,60,026 words in the Training set.

Validation Set:

val.zip contains folder named “images” with 61,230 word level images, and “val_gt.txt” containing image name and ground truth text separated by “Tab space”.

Test Set:

test.zip contains folder named “images” with 1,22,460 word level images, and “test_gt.txt” containing image name and ground truth text separated by “Tab space”.
