Releasing an Improved Blood Count and Cell Detection (BCCD) Dataset
Computer vision is revolutionizing medical diagnoses by assisting doctors with patterns they may not have seen or identifying an error they may have overlooked.
Thus, it's unsurprising one of the more popular "hello world" datasets of object detection is the blood count and cell detection dataset

Eliminating Boilerplate Code with Roboflow to Monitor Security Camera Footage
By using Roboflow, data scientist Alaa Senjab reduced his time to train a custom object detection model detecting guns in security camera footage while increasing machine learning model accuracy.
Highlights:
* Validating image annotation quality, and automated correction of error-inducing improper labels
* Preprocessing and augmentation techniques improving model generalizability
* Automated generation

You Might Be Resizing Your Images Incorrectly
Resizing images is a critical preprocessing step in computer vision.
Principally, our machine learning models [https://models.roboflow.ai] train
faster on smaller images. An input image that is twice as large requires our
network to learn from four times as many pixels — and that time adds up.
Moreover, many
