MJPEG Video Dataset

Legend: *.ascii - data (image size) in 'matrix' format. First row: number of rows, number of columns. Next rows: values. Interpretation: Each row represents a compression level, each column represents the size of the corresponding frame in all compressions. *.bw - bandwidth The files are divided into test and training sets, and their name contains information about the video they belong to. The provided legend describes the format of two types of files: *.ascii and *.bw. The *.ascii files contain data in matrix format, where the first row specifies the number of rows and columns, and the following rows contain the values. Each row represents a compression level, and each column represents the size of the corresponding frame in all compressions. The *.bw files contain bandwidth data. The files are split into two sets: test and training. The name of the file indicates the video it belongs to. These data sets can be used for a variety of purposes, such as testing and training algorithms for video compression or bandwidth estimation.说明： *.ascii 为「矩阵」格式的数据（图像尺寸）。首行标注行数与列数，后续各行存储具体数值。 数据释义：每行对应一种压缩等级，每列对应所有压缩方案下对应帧的尺寸。 *.bw 对应带宽数据。 本数据集包含两类文件：*.ascii与*.bw。其中*.ascii文件采用矩阵格式存储数据，首行指定行数与列数，后续各行存储具体数值；每行代表一种压缩等级，每列代表全部压缩方案中对应帧的尺寸。*.bw文件存储带宽相关数据。 所有文件均被划分为测试集与训练集，文件名中包含其所属视频的相关信息。 本数据集可应用于多种场景，例如视频压缩或带宽估计算法的测试与训练。
