Introduction

Introducing Ben a shopkeeper who delivers services through an online ecommerce store.He provides free return shipping since online clients prefer to shop from ecommerce stores that offer it.

Many customers ordered things online and returned them if they were dissatisfied with what they received or just changed their minds.He was recurring huge losses.

According to Snap's Global Product Marketing Lead, businesses lose up to $550 billion every year due to customer returns.

Mckinsey discovered that 70 percent of returns were due to poor fit or style, implying that shopping tools are an important tool for reducing returns and increasing consumer experience.

This was problematic until virtual try-on came into picture.Ben's return rate has dropped drastically since the ecommerce site introduced the virtual try-on feature.

It has an impact on the retail industry by providing a more accurate portrayal of how virtual try-on garments and accessories will fit and look.

VTO (Virtual Try-On) technology greatly reduces the possibility of returns, which benefits both customers and retailers.Let's take a deep dive into virtual try-on with this blog.

Computer Vision in Visual Try-On?

  • Cameras record your movements and identify the garments you pick up.
  • Advanced algorithms generate an accurate digital avatar of your body form and size, guaranteeing that virtual garments fit correctly.
  • Clothes scanned into the system are quickly recognised, even without barcodes, allowing you to mix and match with ease.
  • Fabrics with unique textures and movements are precisely replicated on your avatar, giving the impression that you are truly wearing them.
  • The virtual lighting adjusts to match the real world, resulting in a seamless and realistic experience.
  • Your avatar mimics your movements in real time, allowing you to see how your garments flow and respond as you stroll, spin, or strike a pose.
  • AI analyses your preferences and previous purchases to recommend designs and colours that you might enjoy, almost like having a virtual stylist by your side.
  • Experiment with different colours, patterns, and even personalised designs on your avatar before purchasing the real thing.
  • Virtually compare different sizes and styles to get the right fit, which reduces returns and waste.

Building the Model

1.Data Collection

  • Ensure that your dataset contains a varied selection of clothing pieces, such as shirts, bottoms, dresses, and accessories. Include changes in patterns, colours, and textures to improve the model's capacity to handle a variety of products.
  • Take photos or videos of different models wearing the apparel goods. This covers different body kinds, sizes, and forms to accommodate a wide range of users.
  • Capture Images or movies of models from various perspectives and poses. This is essential for training the model to comprehend how clothing fits and appears from various angles.
  • Make sure that the videos and images are of high quality. Clarity and detail in data are critical for effective visual simulations. High-resolution photos allow the model to capture detailed features of the clothes.
  • Pre-defined datasets are also available on a variety of websites, including Kaggle,UC Irvine Machine Learning Repository,Dataset Search etc.

2.Data Annotation

  • Annotate the dataset with relevant data such as important spots on clothing items, body landmarks, and any other details required to train the model. This annotated data is critical to supervised learning.
  • Use bounding boxes to highlight each item's location while detecting objects.
  • Use professional annotation software or platforms to streamline and ensure uniformity. Either a manual approach or specific annotation tools like Labellerr can be utilised for this.

3.Model Selection

Options include:

The option is determined by criteria such as dataset qualities, computational resources, and use case requirements.

4.Model Training

  • Divide your data into training and validation sets to assess model performance.
  • Feed your data to the model in batches so it can learn and change its internal parameters.
  • Experiment with different learning rates, optimizer, and other parameters to see how they affect performance.
  • The loss function measures how wrong the model's predictions are, and the optimizer instructs it to minimize that error. Cross-Entropy loss and the Adam optimizer are two popular options.
  • To analyze progress during training, keep track of metrics like accuracy, precision, and recall.

5.Model Optimization

Optimization entails improving the architecture and parameters to enhance realism and user experience.
