3. Problem Statement
To survey and explore some of the methods that can be
used to create a modular pipeline for a virtual try-on
system and to understand the existing one, to make a
productive solution for $1.5 Trillion eFashion Industry.
GOALS
We assigned the following goals for our project:
1. An extensive survey of the papers regarding
technologies that can be used in the fashion industry.
2. Perform cloth parsing on images using instance
segmentation models.
3. Understand the existing virtual-tryon systems.
4. Develop methods to perform human cloth size
estimation.
5. Deploying a feasible solution.

19. Mask RCNN

20. Mask RCNN
For a given image I and class C,
1. C is predicted to be contained in I if IoUC
>= Ө, where Ө is the IoU
threshold
2. Precision and Recall are calculated over all classes for a set of test
images for some given values of Ө
3. MP and MR are used to calculate F1 score.

30. Accomplishments
1. Learned and understood the fundamentals
of necessary technology.
2. Found and understood appropriate
technologies/research for our pipelines.
3. Implemented few methods based on UNet,
Mask-RCNN and OpenPose
4. Proposed few intermediate processes.

31. Issues Faced
1. The mathematical details regarding the
workings of the virtual tryon models
proved to be out of scope for us, and
hence we weren’t able to proceed to
create a version of our own.
2. The multi-class implementation of U-Net
gave poor performance on the test
images, and the faults weren’t clear, and
hence we proceeded with a single class
implementation only.
3. Good dataset was not available to check
to experiments, train and validated our
proposed body shape model.
4. Lack of depth sensing hardware.
5. Computational very expensive units.
6. Restrictions and challenges due to
uncertain events due to COVID-19.

32. Future work
1. To gain better mathematical understanding
behind VITON and ACGPN
2. To understand and design cloth wrapping
modules.
3. To prepare a good size dataset
4. To design and optimise the model such that it
can work on a mobile device with a primitive
GPUs.
5. To extend the capabilities to AR.

33. CONCLUDING REMARKS
1. This BTP was a great learning experience and
have gained much insights of the field.

4. Special Thanks to Dr. Anand Mishra for the
constant support and encouragement.
5. We would be further continuing work in the
area, goal is to make it in hands of users.
