My research interests lie at the intersection of computer vision and machine learning,
with the goal of building human-level computer vision systems that can understand, model, and recreate
the visual world around us. I am working on algorithms for
general visual representation that can be adapted to all kinds of tasks that
require visual input (object recognition, segmentation, synthesis, ...) and also
reduce the need for intensive manual labeling efforts.
For my Ph.D research, I recieved the Concordia University Doctoral Graduate Fellowship as well as the
International Tuition Award of Excellence. In my MASc, I recieved the two-year
MITACS Accelerate Fellowship. 🧠 👀
I have an interest in open-source software and teaching. I have contributed feature code to
the computer vision library Kornia. I also
contributed tutorial code to the popular neural networks library
TensorFlow, Keras which also got featured in
Henry AI Labs and is used as an official demo for
reproducible open-source machine learning . I've also built some
Pynotify: A Python package to send emails and
Boss Detector: Changes monitor screen when your boss is near. 😬
I support Slow Science.
VISTA: Vision Transformer enhanced by U-Net and Image Colorfulness Frame Filtration for Automatic Retail Checkout
Leaderboard (3rd place)
Authors : Md. Istiak Hossain Shihab†, Nazia Tasnim†, Hasib Zunair†, Labiba Kanij Rupty, Nabeel Mohammed († equal contribution)
AI City Challenge, CVPR Workshops, 2022
Given a frame from a video sequence, we first segment single product item and hand followed
by entropy masking to address the domain bias problem, and then a
Vision Transformer (ViT) for multi-class classification. We also propose a custom metric that
discards frames not having any product items, utilizing several image
processing methods.Our method achieved 3rd place in the AI City Challenge, Track 4.
Knowledge distillation approach towards melanoma detection
Authors : Md Shakib Khan, Kazi Nabiul Istla, Abdur Rab Dhruba, Hasib Zunair, Nabeel Mohammed
Computers in Biology and Medicine, 2022
Proposed a knowledge distillation approach for melanoma detection to reduce model complexitiy and enable
easier deployment in edge devices. The proposed method requires relatively less time to detect melanoma. The method
is 15 times smaller than EfficientNet-B0 and consistently achieves better performance in both melanoma and non-melanoma detection.
Designing Efficient Deep Learning Models for Computer-Aided Medical Diagnosis
Authors: Hasib Zunair
Masters Thesis, 2021
Annotating medical image data is time consuming, costly and error prone, and
the scarcity of labeled data limits the effectiveness of supervised learning.
This thesis introduces methods to address the scarcity of labels as well as
class imbalance which results in a bias towards to over-represented class for tasks
such as classification, binary and multi-class semantic segmentation.
Sharp U-Net: Depthwise convolutional network for biomedical image segmentation
Authors : Hasib Zunair, A. Ben Hamza
Computers in Biology and Medicine, 2021
Sharp U-Net achieves improved performance on six medical image segmentation datasets
in both binary and multi-class segmentation tasks while adding no extra learnable parameters.
The idea is instead of applying a plain skip connection,
a depthwise convolution of the encoder feature map with a sharpening kernel filter is done prior to merging the
encoder and decoder features.

ACM Workshop on Multimedia Content Analysis in Sports, 2021
An efficient semi-supervised learning method is proposed for binary and multi-class image classification.
The method requires 6x less compute time and 5x less memory compared to prior arts. We also show that our method
boosts robustness of visual classification models, even without specifically optimizing for adversarial robustness.

Automating the tasks of detecting, segmenting, and classifying cell nuclei can free up the pathologists’ time
for higher value tasks and reduce errors due to fatigue and subjectivity. This paper summarizes and publicly releases
the challenge dataset, and compile key findings of the
methods developed by various participants.

Propose synthetic image data by leveraging class conditioning and adversarial training that achieve results
comparable to training with only real data when using a test set of real images. Also combine synthetic data
with different sizes of real datasets for additional performance gains.
Automatic segmentation of blood cells from microscopic slides: A comparative analysis

Tissue and Cell, 2021
This work proposes a blood cell segmentation dataset consisting of multiple cell types.
Additionally, all cell types
do not have equal instances, which encourages researchers to develop algorithms for
learning from imbalanced classes in a few shot learning paradigm. We also provide both learning and non-learning based
methods as baselines.
