###dcv_createsamples

As a wrapper for opencv_createsamples, this utility allows creating samples in

a folder in a batch automated way.

    positional arguments:

    positives             Path to folder containing source images, or file

                          listing paths to source images.Source object image(s)

                          - (e.g., a company logo).

    optional arguments:

    -h, --help            show this help message and exit

    --bg BG               Background description file; contains a list of images

                          which are used as a background for randomly distorted

                          versions of the object.

    --num NUM             Number of positive samples to generate.

    --bgcolor BGCOLOR     Background color (currently grayscale images are

                          assumed);The background color denotes the transparent

                          color.Since there might be compression artifacts, the

                          amount of color tolerance can be specified by

                          -bgthresh.All pixels withing bgcolor-bgthresh and

                          bgcolor+bgthresh range are interpreted as transparent.

    --bgthresh BGTHRESH   background_color_threshold

    --inv                 If specified, colors will be inverted.

    --randinv             If specified, colors will be inverted randomly.

    --maxidev MAXIDEV     Maximal intensity deviation of pixels in foreground

                          samples.

    --maxxangle MAXXANGLE

                          max_x_rotation_angle

    --maxyangle MAXYANGLE

                          max_y_rotation_angle

    --maxzangle MAXZANGLE

                          max_z_rotation_angle

    --show                Useful debugging option. If specified, each sample

                          will be shown. Pressing Esc will continue the samples

                          creation process without.

    --width WIDTH         Width (in pixels) of the output samples.

    --height HEIGHT       Height (in pixels) of the output samples.

    ---info INFO          Description file of marked up images collection.

**NOTE: ** If you use the utility to select the objects you want to detect, here are further instructions:

- Pressing ESC will cause the program to stop, which can let you restart the program

- Pressing ENTER will allow you to advance to the next image

- Using the mouse, you can select the objects you want to select for creation of the samples.
