Eos 70d dslr camera

Dough rise was recorded with a Canon EOS 70D DSLR camera set to image every two minutes for 36 hr. The camera was centered at the vertical and horizontal midpoint of each dough batch. Timelapse photos were compiled, cropped, and enhanced for contrast using Adobe AfterEffects. The top of every dough was tracked through each frame in the MatLab-based digitizing program DLTdv5 (Hedrick, 2008 (link)). The height of each culture tube (T_h) was measured in pixels in Adobe Photoshop. Changes in dough height (∆X) were normalized to account for distance from the camera and differences in starting height using the following formula: ∆X = (X-X_º)/T_h. Distances relative to tube length were converted to absolute distance (mm/hr) by multiplying values by the dimensions of culture tubes (103 mm). Before fitting curves, data was truncated to cut instances where dough fell by more than 5 percent of its maximum height. For each replicate, a logistic growth curve was fitted, and growth rate (r) was calculated with the R package Growthcurver (Sprouffske and Wagner, 2016 (link)), with a goodness of fit cutoff for r values of p≤0.01.

We constructed a spontaneous and posed smile database to train the proposed 3D CNN model. The spontaneous and posed smile videos were obtained from 88 adults aged 20–80 years. While their facial movements were recorded with a camera, the participants watched a movie clip about 1 min-long to elicit happy emotions. The spontaneous smile videos were obtained by recording genuine smiles that appeared when the participants felt happy while watching a 1 min-long movie clip, while the posed smile videos recorded forced smiles that were induced through verbal commands without a feeling of happiness. Thus, the posed smiles were command-induced expressions, and the spontaneous smiles emerged spontaneously without any command. In addition, to acquire the neutral expressions used in our proposed method, we showed the participant a video without emotional stimulation, induced the participant’s non-expressive state, and acquired a neutral expression video. These smile videos were recorded by a Canon EOS 70D DSLR camera with a 50 mm prime lens, 720 p resolution, and 30 fps frame rate. All participants provided written informed consent prior to the experiment. This study was conducted in accordance with the declaration of Helsinki, and all experiments involving facial behaviors were approved by the institutional review board of the SMG-SNU Boramae medical center (irb no.30-2017-63).
