Introduction #
The authors of the PASCAL Context dataset conduct a comprehensive investigation into the significance of context within existing state-of-the-art detection and segmentation methodologies. Their approach involves the meticulous labeling of every pixel encompassed within the PASCAL VOC 2010 detection challenge, associating each pixel with a semantic category. This dataset is envisioned to present a considerable challenge to the research community, as it incorporates an impressive 520 additional classes that cater to both semantic segmentation and object detection.
Note, that there are 42 unlabeled classes in the dataset.
The authors delve into the role of context in perceptual inference, emphasizing the natural proficiency of humans in comprehending the visual world. Context serves as a pivotal statistical feature of the world, enhancing the efficiency and precision of perceptual inference tasks. Previous cognition-based studies have underscored the role of context in diverse perceptual tasks, including object detection, semantic segmentation, and scene classification. The authors emphasize the influence of contextual information, such as object arrangements in specific scenes, relative object size, and location, on human object detection. Additionally, the authors cite studies demonstrating that humans exhibit superior performance in perceptual tasks when contextual information is available, including object segmentation and image patch classification. The authors aim to delve further into the effect of context within detection and segmentation approaches, setting the stage for their investigation by meticulously labeling every pixel within the training and validation sets of the PASCAL VOC 2010 detection challenge with a semantic class. PASCAL is selected as the testbed due to its prominent role as a benchmark for detection and segmentation in the research community.
The authors’ analysis substantiates the heightened challenge of their dataset compared to alternatives, attributing this challenge to factors such as higher class entropy and a greater diversity of object categories. Their dataset features pixel-wise labels for the 10K trainval images from the PASCAL VOC 2010 detection challenge, encompassing 540 categories divided into objects, stuff, and hybrid classes. The painstaking annotation process spanned three months and involved six in-house annotators, resulting in highly accurate segmentations. These annotations surpass the quality of those generated through online systems like MTurk. Annotators were presented with an initial set of 80 labels and encouraged to introduce additional classes for cases not covered by the initial set. In instances of ambiguity, regions were labeled as “unknown.” Each annotation underwent a double-check, with necessary revisions to ensure coherence. Following a power law distribution, the most frequent 59 classes were selected for analysis, while the remaining classes were assigned the background label. Notably, the vast majority of pixels, approximately 87.2%, were labeled as foreground, contrasting with only 29.3% of pixels covered by the 20 object classes within PASCAL VOC. A distribution of pixels and images among the 59 most frequent categories is visually presented:
Summary #
PASCAL Context Dataset is a dataset for a semantic segmentation task. It is applicable or relevant across various domains.
The dataset consists of 10103 images with 65937 labeled objects belonging to 459 different classes including person, unknown, tree, and other: sky, building, ground, wall, grass, floor, table, pole, chair, car, dog, road, fence, cat, light, water, cloth, sofa, bottle, window, mountain, picture, bird, pottedplant, aeroplane, and 431 more.
Images in the PASCAL Context dataset have pixel-level semantic segmentation annotations. All images are labeled (i.e. with annotations). There are 2 splits in the dataset: val (5105 images) and train (4998 images). The dataset was released in 2014 by the Stanford University.
Here is a visualized example for randomly selected sample classes:
