Counting moving objects is one of the most popular use cases in computer vision. It is used, among other things, in traffic analysis and as part of the automation of manufacturing processes. That is why understanding how to do it well is crucial for any CV engineer.
Roboflow supports tiling during training as a pre-processing step to train
models to detect small objects in large images
[https://blog.roboflow.com/detect-small-objects/], and now you can also use
One of the best parts about joining Roboflow [https://roboflow.com/careers] is
doing a computer vision project in your first 2 weeks. As someone who loves to
workout, I
At Roboflow, we often get asked, what is the train, validation, test split and why do I need it? The motivation is quite simple: you should separate you data into train, validation, and test splits to prevent your model from overfitting and to accurately evaluate your model.
A bedrock of computer vision is having labeled data. In object detection
[https://blog.roboflow.com/object-detection/] problems, those labels define
bounding box positions in a given image.
As computer
Adding contrast to images is a simple yet powerful technique to improve our
computer vision models. But why?
When considering how to add contrast to images and why we add
The recommended Roboflow setting is "Auto-Orient: Enabled"When should you
auto-orient your images?
The short answer: almost always.
When an image is captured, it contains metadata that dictates the orientation
Roboflow [https://roboflow.ai] improves datasets without any user effort. This
includes dropping zero-pixel bounding boxes and cropping out-of-frame bounding
boxes to be in-line with the edge of an image.

The appeals of synthetic data are alluring: you can rapidly generate a vast amount of diverse, perfectly labeled images for very little cost and without ever leaving the comfort of your office. The good news is: it's easy to try! And we're about to show you how.
Knowing how an image preprocessing [https://blog.roboflow.com/tag/preprocessing/] step or

Flipping an image (and its annotations) is a deceivingly simple technique that
can improve model performance in substantial ways.

We seek to build computer vision models [https://models.roboflow.ai] that
