VNPR(Vehicle Number Plate Recognition)\n\n# Project Objectives\n\n* Developed a program to recognize automatic license plates based on limited dataset.\n\n* Localized license plate by applying morphological operations and utilizing contour properties.\n\n* Segmented character-like regions of the license plates by applying perspective transforms, performing a connected component analysis, and utilizing contour properties.\n\n* Scissored the true characters from previous step by pruning extraneous license plate character candidates, and extracting each character from binary image to create a training set for building classifiers.\n\n* Extracted BBPS features from the training set and Built two SVM classifiers for recognizing the letters and numbers of the license plate.\n\n# Software/Packages Used\n\n\n\n# Algorithms \u0026 Methods Used\n\n* License plate localization\n  * Apply morphological operations to reveal possible license plate region.\n    * Blackhat operation\n    * Sobel gradient\n    * Otsu automatic thresholding\n    * Erosion \u0026 dilation\n  * Utilize contour properties to prune license plate candidates.\n* Characters segmentation\n  * Apply perspective transform to extract license plate region from car, obtaining a top-down, bird’s eye view more suitable for character segmentation.\n    * 4-point transform\n    * Adaptive thresholding\n  * Perform a connected component analysis on the license plate region to find character-like sections of the image.\n    * 8-connectivity component analysis\n    * Convex hull\n  * Utilize contour properties to segment the foreground license plate characters from the background of the license plate.\n* Character Scissoring\n  * Develop and implement a heuristic to prune extraneous license plate character candidates, leaving with only the real characters.\n  * Define a method to extract each of the license plate characters from the binary image.\n* Character Classification\n  * Extract and label license character examples from license plate dataset.\n  * Extract block-binary-pixel-sum (BBPS) features from real-world license plate character examples.\n    * Block-binary-pixel-sum descriptor\n  * Train two classifiers on the BBPS features: one classifier for letter recognition and a second classifier for digit recognition.\n    * Support vector machine\n\n## Support Me\nIf you
