Lung Cancer Lesion Detection in Histopathology Images Using Graph-Based Sparse PCA Network

no code implementations27 Oct 2021 Sundaresh Ram, Wenfei Tang, Alexander J. Bell, Cara Spencer, Alexander Buschhaus, Charles R. Hatt, Marina Pasca diMagliano, Jeffrey J. Rodriguez, Stefanie Galban, Craig J. Galban

In this paper, we propose a simple machine learning approach called the graph-based sparse principal component analysis (GS-PCA) network, for automated detection of cancerous lesions on histological lung slides stained by hematoxylin and eosin (H&E).

Robust Segmentation of Cell Nuclei in 3-D Microscopy Images

no code implementations7 Oct 2021 Sundaresh Ram, Jeffrey J. Rodriguez

Like other segmentation algorithms, we first use a seed detection/marker extraction algorithm to find a seed voxel for each individual cell nucleus.

Object sieving and morphological closing to reduce false detections in wide-area aerial imagery

no code implementations28 Oct 2020 Xin Gao, Sundaresh Ram, Jeffrey J. Rodriguez

We use two wide-area aerial videos to compare the performance of five object detection algorithms in the absence and in the presence of our post-processing scheme.

Drive-Net: Convolutional Network for Driver Distraction Detection

no code implementations22 Jun 2020 Mohammed S. Majdi, Sundaresh Ram, Jonathan T. Gill, Jeffery J. Rodriguez

To help prevent motor vehicle accidents, there has been significant interest in finding an automated method to recognize signs of driver distraction, such as talking to passengers, fixing hair and makeup, eating and drinking, and using a mobile phone.

Joint Cell Nuclei Detection and Segmentation in Microscopy Images Using 3D Convolutional Networks

no code implementations8 May 2018 Sundaresh Ram, Vicky T. Nguyen, Kirsten H. Limesand, Mert R. Sabuncu

Mirroring the co-dependency of these tasks, our proposed model consists of two serial components: the first part computes a segmentation of cell bodies, while the second module identifies the centers of these cells.
