Table 1 Main parameters in the generation processes
From: First-person reading activity recognition by deep learning with synthetically generated images
Process | Parameters | Values |
|---|---|---|
– | Canvas of each page | \(210\sqrt {2} \times 210\) pixel by appropriate scaling |
T | Blank space | 10% at the top, bottom, left, and right in the canvases |
Columns | 1 or 2 | |
Pages containing figures | 80% of the entire generated pages | |
Place to put figures | The top or the bottom in a column | |
Category of figures | Mathematical figures, tables, and general pictures | |
Figure size | Height: 12.5∼50%, or 100% of the column height | |
Width: fixed at the same length of the column | ||
Size of headlines | 10% of the page height | |
Place to put headlines | Somewhere outside the figure areas | |
Place to put texts | Entire areas in the column except the figures and headlines | |
Text format | Japanese characters in random order (without any rules) | |
Line-breaking | Done with prob. 1% every time putting a character | |
D | Distortion strength | α∈[0.1,0.3] |
P | Homography matrix | Determined as shown in Fig. 4 |
R | Rotation angles | In [ − 10°,10°] |
– | Resize | The long side shrinks to 256 pixel with keeping the ratio |
