## Pascal VOC
|
| 9 |
+
#### Dataset Summary
|
| 10 |
+
The Pascal Visual Object Classes (VOC) dataset is a widely used benchmark in the field of computer vision. It is designed for object detection, image classification, semantic segmentation, and action classification tasks. The dataset provides a comprehensive set of annotated images covering 20 object classes, allowing researchers to evaluate and compare the performance of various algorithms.
|
| 11 |
+
**Note**: This dataset repository contains all editions of PASCAL-VOC, each file is identified with the year.
|
| 12 |
+
|
| 13 |
+
#### Dataset Structure
|
| 14 |
+
**Images:** The dataset contains 178k images.
|
| 15 |
+
**Annotations:** Annotations include object bounding boxes, object class labels, segmentation masks, and action labels.
|
| 16 |
+
**Classes:** 20 object classes: person, bicycle, car, motorbike, aeroplane, bus, train, boat, bird, cat, dog, horse, sheep, cow, elephant, bear, zebra, giraffe, and potted plant.
|
| 17 |
+
**Supported Tasks**
|
| 18 |
+
**Image Classification:** Assigning a label to an image from a fixed set of categories.
|
| 19 |
+
**Object Detection:** Identifying objects within an image and drawing bounding boxes around them.
|
| 20 |
+
**Semantic Segmentation:** Assigning a class label to each pixel in the image.
|
| 21 |
+
**Action Classification:** Identifying the action being performed in the image.
|
| 22 |
+
|
| 23 |
+
#### Applications
|
| 24 |
+
The Pascal VOC dataset is used for:
|
| 25 |
+
|
| 26 |
+
- Benchmarking and evaluating computer vision algorithms.
|
| 27 |
+
- Training models for image classification, object detection, and segmentation tasks.
|
| 28 |
+
|
| 29 |
+
#### Data Collection and Annotation
|
| 30 |
+
|
| 31 |
+
**Data Sources**
|
| 32 |
+
The images were collected from Flickr and other sources, ensuring a diverse and representative sample of real-world scenes.
|
| 33 |
+
|
| 34 |
+
A**nnotation Process**
|
| 35 |
+
Annotations were carried out by a team of human annotators. Each image is labeled with:
|
| 36 |
+
|
| 37 |
+
- Bounding boxes for object detection.
|
| 38 |
+
- Class labels for each object.
|
| 39 |
+
- Pixel-wise segmentation masks for semantic segmentation.
|
| 40 |
+
- Action labels indicating the action performed by the objects in the image.
|
| 41 |
+
|
| 42 |
+

|
| 43 |
+
The Pascal VOC dataset is released under the Creative Commons Attribution 2.5 License. Users are free to share, adapt, and use the dataset, provided appropriate credit is given.
