 ## A Brief of the Prototype:
-  This section must include UML Daigrms and prototype description
+
+In the domain of autonomous cars, object detection for self-driving vehicles is a major challenge. It must be able to precisely detect and identify objects in its surroundings, such as pedestrians, other cars, traffic signs, and barriers, in order to function safely and effectively.
+
+By utilizing Intel OneAPI, the main objective of this project is to develop a reliable, accurate, and effective object detection system that will support the development of the next generation of autonomous vehicles.
+
+to achieve this goal we are using state of the art U-net. which is quite good model for instance segmentation. we are trying to train this model on a little part of city scape dataset. once we train the model we will try to optimize it using oneAPI. we will record the data for both of the scenarios and onece we are done we will make this data available on this repository.

+architecture of U-net

+
+
+real time detection can also be perfrmed like shown in this diagram

 ## Step-by-Step Code Execution Instructions:
-  This Section must contain set of instructions required to clone and run the prototype, so that it can be tested and deeply analysed
-
+step-1 : clone this repository
+step-2 : run train.py

 ## What I Learned:
-   Write about the biggest learning you had while developing the prototype
+I learnt how to work with Intel oneapi and devcloud. Intel oneapi has also given me a chance to explore various different libraries and toolkits that had helped us to optimize the performance of our model.
