3. Dataset comparison

3.1 MD-fashion vs. Deepfashion

In terms of total data volume, MD has more data volume of about 360w, while DeepFasion has 80w. DeepFasion was released in 2016, and its image content is a little outdated, and lacking in fashionable clothing styles. MD’s data content is the latest collection from the Internet, fashion shows ,and so on. In terms of image labeling, DeepFasion lacks Mask labeling. In terms of detection, key points are used as labeling information and only three detection categories are included (top, bottom and whole body). MD covers a large number of key points, Mask annotation, and segmentation annotation category is more than 30, so it is more fine-grained. Deepfashion segmentation labeling has only one category in a picture, while MD contains multiple categories. Deepfashion also provides annotation data for the text retrieval image task, and provides a detailed description of clothing attributes. Md-fashion provides a classified dataset for clothing material, which is convenient for the computer to further understand clothing.

3.2 MD-fashion vs. Deepfashion2

Firstly, MD is superior to Deepfashion2 in total dataset. The DeepFasion2 segmentation dataset contained 49.2W larger than MD21.1W, but the MD segmentation dataset contained more segmentation categories, not only the labeling of clothing, but also the labeling of accessories such as human body and mobile phone. The classification of MD segmentation was 30, which was better than DeepFasion2’s 13. Deepfashion2 also retains text descriptions for clothing.

4. Trends In Fashion Datasets

With the rapid development of e-commerce platforms, clothing category has become a trillion-level market. With more than $30 billion in apparel sales on Amazon’s platform in 2018, it has surpassed Walmart to become the no. 1 apparel retailer in the United States. The COVID-19 epidemic in 2020 did not change the trend of market development, but further accelerated the pace of business reform and promoted the emergence of more new consumption patterns in the clothing market. Consumers are more receptive to online retail channels than before the epidemic, digital transformation of physical retailers is in full swing, and new consumer innovations such as live delivery, online experience and the sharing economy are in full swing.

The demand characteristics of the clothing category are closely related to the gender, age, ethnicity, region ,and consumption ability of the crowd. Buyers’ demand for clothing is actually diversified and fragmented. With the increase in clothing styles and the enrichment of application scenarios, the existing public datasets are evolving toward the following:

  • Multiple Tasks.
  • Larger Volume. To some extent, deep learning is based on data-driven approaches. Massive data plays an important role in model learning and understanding.
  • Fine-Grained Annotation. It is manifested in the refinement of segmentation and classification. In the segmentation task, some accessories and other small objects are added to the mark, and the classification task expands the categories.

 

4.1 Multiple Tasks

Early Fashion datasets may only contain classification tasks. For example, fashion-Minst3 resampling JPEG images with a resolution of 762*1000 to obtain grayscale images with a resolution of only 28*28, such early datasets only marked the categories of clothing and other information suitable for classification tasks. After the launch of Deep Fashion, it added annotation information such as text description, Bbox and landmark, which also means that this dataset can be used for text retrieval and object detection task training. Md-fashion and Deep Fashion2 further provide Mask annotation, and continue to expand the task category to semantic segmentation to complete more fine-grained object detection tasks. The emergence of Deep Fashion 3D adds  3D scanning data to the dataset of Fashion series, which can deal with the 3D reconstruction tasks derived from the increasingly popular metasexes and virtual image scenes.

At present, the Fashion dataset already includes classification, segmentation, detection, generation, cross-modal retrieval, 3D reconstruction and other existing task annotations, and it may continue to increase in the future.

 

4.2 Larger Volume

In the task definition of supervised learning, deep learning can be regarded as a data-driven process, and massive and diverse data is of great significance to the improvement of network performance. With the development of time and the deepening of fashion research, the number and volume of datasets are also increasing exponentially, not only because of the increasing demand for application scenarios, but also because of the development of distributed training and the improvement of GPU storage capacity. The original fashion-Minst consisted of 6W training images and 1W test images, followed by Deep Fashion with 80W images and WAB with 104W images. Md-fashion has maintained the largest number of images at 360W so far.

Since Fashion dataset is different from other datasets such as animal species and fruit species, Fashion dataset has strong timeliness to a certain extent. For example, some latest styles, some new clothing materials, clothing accessories and so on will be updated over time, so the number of Fashion datasets will continue to be updated and tend to be larger in the future.

 

4.3 Fine-Grained Annotation

With the continuous development of technology and the continuous refinement and specialization of fashion application scenarios, datasets are also developing towards such a trend. For example, in the field of classification, there may be less than five categories before, but now MD-Fashion has increased to 80 categories. The previous classification was more focused on the attributes of clothing, such as short sleeves, jackets and trousers, but now the dataset has added more refined classification of clothing materials, such as cotton and silk. In the field of segmentation, the early DeepFashion series only had three types of segmentation, but now MD-Fashion supports up to 30 categories of classification labeling in one picture, which is more professional. In the aspect of detection, coordinate estimation is no longer limited to the object itself, and the key point estimation of clothing pattern is added.

The continuous specialization and refinement of Fashion application field requires more fine-grained labeling information to better meet downstream tasks.
