MCL Research on Nuclei Image Segmentation

Nuclei Segmentation is a key step in understanding the distribution, size, and shape of nuclei in the underlying tissue. Traditionally, pathologists view histology slides under the microscope to analyze the nuclei structure. However, this process is time-consuming and is prone to inter-reader variability. An AI-based segmentation algorithm aids pathologists in cancer detection and prognosis and helps speed up the cancer screening procedure. 

While there are several deep learning methods addressing this problem, we propose a Green Nuclei Segmentation algorithm that uses a simple, reliable, and modular approach to delineate nuclei in a histopathology slide. The Green U-shaped Learning algorithm features an encoder-decoder style architecture. The encoder learns local and global features from each image, and the decoder predicts an initial mask at a coarse resolution and refines the predictions as we progress from the coarse to fine resolution. We aim to predict a binary mask that separates the nuclei from the rest of the cell material.

MCL’s Thanksgiving Luncheon

For over 20 years, the Thanksgiving Luncheon has been a cornerstone of MCL’s community spirit, offering a chance to celebrate gratitude and connection. This year, on November 28, 2024, the tradition continued as the MCL family gathered at Shiki Seafood Buffet to share a memorable meal.

The luncheon was more than just an opportunity to enjoy great food; it was a moment to step away from the daily grind and reconnect with friends and colleagues. The lively atmosphere was filled with laughter and meaningful conversations, reminding everyone of the strength and warmth of the MCL community.

Such an event wouldn’t have been possible without the guidance of Professor Kuo, whose dedication keeps this tradition alive, and the students who put in the effort to ensure everything ran smoothly.

As another Thanksgiving Luncheon joins the books, the MCL family looks forward to many more years of celebration, connection, and gratitude. Happy Thanksgiving to all!

Welcome New MCL Member Fenxiao Chen

We are so happy to welcome a new Ph.D. student, Fenxiao Chen, in Fall 2017. Let us hear what she said about her research and MCL.

1. Could you briefly introduce yourself? (Previous research experience, project experience, research interest and expertise)
I worked on Cloud Computing and distributed systems before. I interned at Berkeley National Lab on DNA k-mer assembly and Artigen Corp on natural language processing.

2. What’s your first impression of USC and MCL?
First impression of USC is that it’s a school that welcomes a great range of diversity. MCL is the largest research group I have seen so far in the EE department. I like the researching environment that is not only encouraging but also inspiring.

3. What’s your future expectation for MCL?
I hope I can develop more expertise on natural language processing and deep learning. With the help of MCL I wish to bring my own contribution as well.

Welcome New MCL Member Harry Yang

We are so happy to welcome a new Ph.D. student, Harry Yang, in Fall 2017. Let us hear what he said about his research and MCL.

1. Could you briefly introduce yourself and your research interests?
My name is Chao “Harry” Yang, and I am a 2nd year Ph.D. student at the MCL lab in the department of computer science at USC. Prior to joining MCL, I was a PhD student at the computer graphics lab of USC. I received my Bachelor’s degree of mathematics in University of Science and Technology of China. I am interested in computer vision and deep learning, and previously I worked on research projects related to image inpainting and domain adaptation.

2. What’s your first impression of USC and MCL?
USC has a beautiful campus and a vibrant research environment. I love to walk in the campus seeing a lot of students and professors full of passion and energy. The MCL lab is a wonderful place with a caring and supportive advisor and a large group of young talented students. I feel more motivated and enthusiastic about my everyday research after joining MCL and I super enjoy the interaction with the professor and group members.

3. What is your future expectation and plan in MCL?
I want to make friends in MCL, do good research and write high-quality papers. I am really excited to be able to learn from everyone in the group. With so much help and support, I am looking forward to a great career ahead of me after finishing my study in MCL.

MCL Students Presented Papers at BMVC 2017

We would like to share the good news that our group has two papers accepted by BMVC 2017 from Qin Huang and Siyang Li. This year BMVC is more competitive than before, according to the conference committee. We are happy that our group successfully has two papers, especially with one as oral presentation.

–Qin Huang, Chunyang Xia, Chihao Wu, Siyang Li, Ye Wang, Yuhang Song and C.-C. Jay Kuo, “Semantic Segmentation with Reverse Attention” (Oral)
–Siyang Li, Xiangxin Zhu, Qin Huang, Hao Xu and C.-C. Jay Kuo, “Multiple Instance Curriculum Learning for Weakly Supervised Object Detection” (Poster)

Here are the Obstructs for the two papers:

“Semantic Segmentation with Reverse Attention”:
Obstruct: Recent development in fully convolutional neural network enables efficient end-to-end learning of semantic segmentation. Traditionally, the convolutional classifiers aretaught to learn the representative semantic features of labeled semantic objects. In thiswork, we propose a reverse attention network (RAN) architecture that trains the net-work to capture the opposite concept (i.e., what are not associated with a target class) aswell. The RAN is a three-branch network that performs the direct, reverse and reverse-attention learning processes simultaneously. Extensive experiments are conducted toshow the effectiveness of the RAN in semantic segmentation. Being built upon theDeepLabv2-LargeFOV, the RAN achieves the state-of-the-art mean IoU score (48.1%)for the challenging PASCAL-Context dataset. Significant performance improvementsare also observed for the PASCAL-VOC, Person-Part, NYUDv2 and ADE20K datasets.

“Multiple Instance Curriculum Learning for Weakly Supervised Object Detection”:
Obstruct: When supervising an object detector with weakly labeled data, most existing ap- proaches are prone to trapping in the discriminative object parts, e.g., finding the face of a cat instead of the full body, due to lacking the supervision on the extent of full objects. To address this challenge, [...]
