# AV-Dataverse-Hack-Build-an-AI-Model-to-Save-Lives

### Competition hosted on Analyticsvidhya

# About

### Build a computer vision-based technology to process and detect the potholes present in an image.

### This is my first object detection - computer vision hackathon. 

### From the competition starter notebook, I have tried the same PyTorch - fasterrcnn resnet50 fpn object detection model, and without the proper image processing or data augmentation the model not performed well and didn't learn any signals. 

### Final Competition score is 0.0060050745

### Leaderboard Rank is 72/77

### Evaluation Metric is mAP@[.5,.95]

### Post-competition I personally tried the yolo object detection model with wandb logging. The model scored 38%(100*mAP[.5,.95]) on test dataset.

    #### Basic Exploratory Data Analysis

    #### Packages Used,

        * seaborn

        * Pandas

        * Numpy

        * Matplotlib

        * PIL

        * cv2

        * os

        * distance

        * imagehash

        * time

        * itertools

    #### Extract basic information about the images(width, height, color mode) and analyzed the information through visualization in the following methods.

    

    #### Total pothole wise image samples.

    #### RGB color distribution analysis.

    #### Find the similar images using different hashing algorithms.

         * Average hashing - Total matched images 284

         * Perceptual hashing - Total matched images 80

         * Difference hashing - Total matched images 80

         * Wavelet hashing - Total matched images 280

         * Color hashing - Total matched images 217120

         

    #### From the above various image hashing algorithm, the perceptual hashing, and difference hashing algorithms significantly find similar images based on the hash value.
