Introduction

A common problem in computer vision is the applicability of the algorithms developed on the meticulously controlled datasets on real world problems, such as unscripted, uncontrolled videos with natural lighting, view points and environments. With the advancements in the feature descriptors and generative methods in action recognition, a need for comprehensive datasets that reflect the variability of real world recognition scenarios has emerged.

This dataset comprises of 10 actions related to breakfast preparation, performed by 52 different individuals in 18 different kitchens. The dataset is to-date one of the largest fully annotated datasets available. One of the main motivations for the proposed recording setup “in the wild” as opposed to a single controlled lab environment is for the dataset to more closely reflect real-world conditions as it pertains to the monitoring and analysis of daily activities.

The number of cameras used varied from location to location (n = 3 − 5). The cameras were uncalibrated and the position of the cameras changes based on the location. Overall we recorded ∼77 hours of video (> 4 million frames). The cameras used were webcams, standard industry cameras (Prosilica GE680C) as well as a stereo camera (BumbleBee , Pointgrey, Inc). To balance out viewpoints, we also mirrored videos recorded from laterally-positioned cameras. To reduce the overall amount of data, all videos were down-sampled to a resolution of 320×240 pixels with a frame rate of 15 fps.

Cooking activities included the preparation of:

  1. coffee (n=200)
  2. orange juice (n=187)
  3. chocolate milk (n=224)
  4. tea (n=223)
  5. bowl of cereals (n=214)
  6. fried eggs (n=198)
  7. pancakes (n=173)
  8. fruit salad (n=185)
  9. sandwich (n=197)
  10. scrambled eggs (n=188).

Current Benchmarks

Fully supervised

The dataset has been a applied to various use cases so far. For fully supervised learning the tasks are Activity classification (classify the full videos according to the 10 activity classes) ans Temporal segmentation (detect and classify the 48 action units within the videos).

Activity classification

Temporal Segmentation

Weakly supervised

For weakly supervised learning, we consider that at training time only the videos with the respective transcripts (the action oder as they occur in the video) are given without any action boundary information.  The tasks are Temporal alignment (the transcripts of the test videos are given at test time and the respective actions need to be detected) ans Temporal segmentation (detect and classify the 48 action units within the videos without transcripts).

Temporal Segmentation
