* Add lambertian sphere brightness model for objects. Set object key `model` `mode` to `lambertian_sphere` and set `albedo` and `size` (meters) parameters. For 2D simulations, `distance` (km) and `phase_angle` (degrees) parameters must also be specified.
0.18.0
---------------------
* Add turbulent atmosphere to POPPY PSF generation. Set with psf option `turbulent_atmosphere` and sim option `psf_sample_frequency`. * Add star and object segmentation annotation. Set sim option `save_segmentation` to `true` and `star_annotation_threshold` to limit stars annotated.
0.17.1
---------------------
* Copy useful TensorFlow Addon (TFA) functions into `tfa` as the TFA project is no longer maintained. * Copy tests.
0.17.0
---------------------
* Add JSON schema definitions. See `schema/v1/Document.json` for root schema file. * Add observation object type. * Add support for cropped sensors. * Add altitude to site object. Set site `alt` parameter in km. Default is 0.
0.16.0
---------------------
* Add option to annotate stars. Set sim option `star_annotation_threshold` to the minimum star brightness magnitude or `false` to disable. Disabled by default. * Add option to show annotated stars in annotated images. Set sim option `show_star_boxes` to `true` to enable.
0.15.1
---------------------
* Remove clipping of negative values in ground truth files by default. * Fix missing dependencies for ground truth file generation.
