Albumentations library in Computer Vision - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the Albumentations library used for in computer vision?

Albumentations is a Python library used to easily apply fast and flexible image augmentations to improve the diversity of training data in computer vision tasks.

beginner

Name three common image augmentations provided by Albumentations.

Common augmentations include flipping images horizontally or vertically, rotating images by some degrees, and changing brightness or contrast.

How does Albumentations help improve machine learning model performance?

By creating varied versions of images through augmentation, Albumentations helps models learn to recognize objects under different conditions, reducing overfitting and improving generalization.

intermediate

What is the typical way to apply multiple augmentations using Albumentations?

You create a Compose object that chains multiple augmentations together, then apply it to images during training.

intermediate

Why is Albumentations preferred over some other augmentation libraries?

Albumentations is fast, easy to use, supports many augmentations, works well with bounding boxes and masks, and integrates smoothly with deep learning frameworks.

What does Albumentations primarily help with in computer vision?

A Image augmentation to increase training data variety

B Building neural network architectures

C Evaluating model accuracy

D Collecting image datasets

Albumentations is designed to apply image augmentations to increase data variety for training.

Which Albumentations function is used to combine multiple augmentations?

A Chain()

B Compose()

C Merge()

D Concat()

Compose() is used to chain multiple augmentations in Albumentations.

Which of these is NOT a typical augmentation in Albumentations?

A TrainTestSplit

B Rotate

C HorizontalFlip

D BrightnessContrast

TrainTestSplit is a data splitting method, not an augmentation.

Albumentations supports augmentations for which of these data types?

A Images only

B Audio data

C Text data

D Images and bounding boxes

Albumentations supports images and related annotations like bounding boxes and masks.

Why is image augmentation important in training computer vision models?

A To reduce dataset size

B To make models faster

C To increase data diversity and reduce overfitting

D To label images automatically

Augmentation increases data diversity, helping models generalize better and avoid overfitting.
