Load video datasets to PyTorch DataLoader

VDataset

Description

Load video datasets to PyTorch DataLoader. (Custom Video Data set for PyTorch DataLoader)
VDataset can be use to load 20BN-Jester dataset to the PyTorch DataLoader

Required Libraries

• torch
• torchvision
• Pillow
• pandas

Arguments for constructor

Argument	Type	Required	Description
csv_file	str	True	Path to .csv file
root_dir	str	True	Root Directory of the video dataset
file_format	str	False	File type of the frame images (ex: .jpg, .jpeg, .png)
id_col_name	str	False	Column name, where id/name of the video on the .csv file
label_col_name	str	False	Column name, where label is on the .csv file
frames_limit_mode	str/None	False	Mode of the frame count detection ("manual", "csv" or else it auto detects all the frames available)
frames_limit	int	False	Number of frames in a video (required if frames_count_mode set to "manual")
frames_limit_col_name	str	False	Column name, where label is on the .csv file (required if frames_count_mode set to "csv")
frames_resize	tuple/None	False	Resize the frames (Also this can be done on using transform too)

Usage

from torch.utils.data import DataLoader
from torchvision import transforms

transforms = transforms.Compose([transforms.Resize((100, 100)),
                                       transforms.ToTensor()])

vdataset = VDataset(csv_file='path-to-csv-file.csv', root_dir='path-to-video-dir', transform=transforms)
dataloader = DataLoader(vdataset, batch_size=64) # use in DataLoader


for image, label in dataloader: # Do what do you want in dataset
    print(image, label)
    break
