Roboflow is an end-to-end computer vision platform that helps you
|
76 |
-
* collaborate with your team on computer vision projects
|
77 |
-
* collect & organize images
|
78 |
-
* understand and search unstructured image data
|
79 |
-
* annotate, and create datasets
|
80 |
-
* export, train, and deploy computer vision models
|
81 |
-
* use active learning to improve your dataset over time
|
82 |
-
|
83 |
-

92 |
-
* Auto-orientation of pixel data (with EXIF-orientation stripping)
|
93 |
-
|
94 |
-
No image augmentation techniques were applied.
