# image-dataset-converter-imgaug
Image augmentation extension for the [image-dataset-converter](https://github.com/waikato-datamining/image-dataset-converter) library.
## Installation
Via PyPI:
```bash
pip install image-dataset-converter-imgaug
```
The latest code straight from the repository:
```bash
pip install git+https://github.com/waikato-datamining/image-dataset-converter-imgaug.git
```
## Tools
### Generate regions
```
usage: idc-generate-regions [-h] -W WIDTH -H HEIGHT [-r NUM_ROWS]
[-c NUM_COLS] [-R ROW_HEIGHT] [-C COL_WIDTH] [-f]
[-p] [-1] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}]
Tool turns an image size into regions to be used, e.g., with the 'sub-images'
filter. Either specify the number of rows/cols or the height/width of
rows/cols.
optional arguments:
-h, --help show this help message and exit
-W WIDTH, --width WIDTH
The width of the image. (default: None)
-H HEIGHT, --height HEIGHT
The height of the image. (default: None)
-r NUM_ROWS, --num_rows NUM_ROWS
The number of rows. (default: None)
-c NUM_COLS, --num_cols NUM_COLS
The number of columns. (default: None)
-R ROW_HEIGHT, --row_height ROW_HEIGHT
The height of rows. (default: None)
-C COL_WIDTH, --col_width COL_WIDTH
The width of columns. (default: None)
-f, --fixed_size Whether to use fixed row height/col width, omitting
any left-over bits at right/bottom, when using
num_rows/num_cols (default: False)
-p, --partial Whether to output partial regions, the left-over bits
at right/bottom, when using row_height/col_width
(default: False)
-1, --one_based Whether to use 1-based coordinates (default: False)
-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}, --logging_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}
The logging level to use. (default: WARN)
```
### Combine sub-images
```
usage: idc-combine-sub-images [-h] -i INPUT [INPUT ...] -g REGEXP -x REGEXP -y
REGEXP -W WIDTH -H HEIGHT [-1] -r CMDLINE [-m]
-w CMDLINE
[-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}]
Tool for combining image regions and annotations generated by the 'sub-images'
filter. NB: it does not combine adjacent annotations.
optional arguments:
-h, --help show this help message and exit
-i INPUT [INPUT ...], --input INPUT [INPUT ...]
Path to the report file(s) to read; glob syntax is
supported (default: None)
-g REGEXP, --group REGEXP
Regular expression for grouping the sub-images into
ones that belong to a single image (first group is
used a group ID) (default: None)
-x REGEXP Regular expression for extracting the x coordinate
(first group) (default: None)
-y REGEXP Regular expression for extracting the y coordinate
(first group) (default: None)
-W WIDTH, --width WIDTH
The width of the image. (default: None)
-H HEIGHT, --height HEIGHT
The height of the image. (default: None)
-1, --one_based Whether the coordinates are 1-based (default: False)
-r CMDLINE, --reader CMDLINE
The reader command-line to use for reading the sub-
images. (default: None)
-m, --merge_adjacent_polygons
Whether to merge adjacent polygons (object detection
only). (default: False)
-w CMDLINE, --writer CMDLINE
The writer command-line to use for writing the
combined images, must contain parameters for storing
the output. (default: None)
-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}, --logging_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}
The logging level to use. (default: WARN)
```
