+# Project Description
+
+Estimating Depth and localizing endoscope in surgical environment is critical in many tasks such as, intra-operative registration, augmented reality, surgical automation, among many others. Monocular self-supervised depth and pose estimation methods can estimate depth and camera pose without requiring labels. However, how do these methods perform in presence of deformation while endoscope moves through the lumen is not known. Therefore, through this project we want to evaluate the effect of addition of primarily two modules on depth and pose estimation accuracy. These modules are TransUnet and Optical Flow Module. Optical Flow can capture the image intensity changes in the scene because of deformation. And TransUnet can potentially capture the temporal correlations between the image frames to give better pose and depth predictions. For the project open sources dataset and github codes will be utilized.

+
+## Objective
+
+
+1. Objective A. To build and run and train the FlowNet on colonoscopy dataset
+1. Objective B. To integrate the flowNet module in the Monodepth2 framework
+1. Objective C. To integrate and evaluate TransUnet blocks in Monodepth2 framework. 
+
+## Approach and Plan
+
+
+1. Run the Monodepth2 on the colonoscopy dataset. 
+1. Train the optical flow network on the coloscopic dataset
+1. 
+
+## Progress and Next Steps
+
+1. Run the model on the coloscopic dataset. 
+2. Run TransUnet
+3. Replace the TransUnet in Monodepth2 and run on the dataset
+
+1. Describe specific steps you **have actually done**.
+1. Initial implementation of optical flow network
+1. Replace the Unet with TransUnet and see its effect of depth and pose prediction
