+# Object Detector
+## Description
+The Object Detector is a computer vision project that uses deep learning algorithms to detect and identify objects in images and videos. This project can be used for a variety of applications, such as security monitoring, autonomous vehicles, and smart home systems.
+
+## Features
+
+1.Supports detection of multiple object classes in a single image or video frame
+
+2.Provides bounding boxes and class labels for each detected object
+
+3.Utilizes a pre-trained deep learning model for fast and accurate object detection
+
+4.Allows for custom training of the object detection model on new datasets
+
+5.Provides an easy-to-use Python API for integrating the object detector into your own projects
+
+## Getting Started
+
+**Prerequisites**
+
+Python 3.6 or higher
+
+TensorFlow 2.x or PyTorch 1.x
+
+OpenCV
+
+## Installation
+
+1.Clone the repository:
+
+
+git clone https://github.com/NANDAGOPALNG/PyVerse/tree/main/Generative-AI/Object%20Detector
+
+2.Install the required dependencies:
+
+
+pip install -r requirements.txt
+
+## Usage
+
+1.Import the object detector module:
+python
+
+
+from object_detector import ObjectDetector
+
+2.Create an instance of the object detector:
+python
+
+
+detector = ObjectDetector()
+
+3.Detect objects in an image:
+python
+
+
+image = cv2.imread('image.jpg')
+detections = detector.detect(image)
+
+4.Visualize the detected objects:
+python
+
+
+for detection in detections:
+
+    x, y, w, h = detection['bbox']
+
+    label = detection['label']
+
+    cv2.rectangle(image, (x, y), (x+w, y+h), (0, 255, 0), 2)
+
+    cv2.putText(image, label, (x, y-10), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (36,255,12), 2)
+
+cv2.imshow('Object Detection', image)
+
+cv2.waitKey(0)
+
