title: BrainGut_WineUp laboratory images [Dataset]

description: DATA & FILE OVERVIEW 1. File List: The DATASET compiles 24.305 files corresponding to individual images of glasses containing red wine. Each file name is unique and contains information of the parameters under which the photograph was taken (see DATA-SPECIFIC INFOR-MATION for details). For example: The file Est_Rio_J_Bor_125_nd_f_bl_sin_al_sup corresponds to a laboratory image (Est), taken in La Rioja (Rio), of a young wine (J), in a Bourgogne wine glass (Bor), with a volume of 125 mL (125), taken at none defined time (nd), under flash lighting (f), with a white background (bl) and no reference object (sin), and at a far distance (al) and upper angle (sup). 2. Relationship between files, if important: No important. 3. Additional related data collected that was not included in the current data package: BrainGut_WineUp everyday images. Dataset, in construction. 4. Are there multiple versions of the dataset? No.
description: METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: The photographs of glasses containing wine were acquired with a mobile phone. They were previously designed considering usual photographic parameters (see DATA-SPECIFIC INFORMATION for details). 2. Methods for processing the data: The data have not been processed. 3. Instrument- or software-specific information needed to interpret the data: Image (or photo) viewer or editor. 4. Standards and calibration information, if appropriate: A reference object (an euro coin) was included in some of the photographs to allow further standardization if required. 5. Environmental/experimental conditions: Photographs were taken under normal laboratory conditions. 6. Describe any quality-assurance procedures performed on the data: Photographs were checked visually at least by two of the authors before being incorporated to the dataset. 7.
