Abstract: Road crashes have been a major problem in India in recent times. The occurrences have increased considerably owing to the influx of four-wheelers and two-wheelers on roads. The interior roads connecting villages and towns have been instrumental in multiple animal-vehicle collisions. Though numerous efforts have been in progress to reduce the number of collisions, lack of practical applications has impeded any major breakthrough in the scenario. In our current work, we designed a system based on histograms of oriented gradients and cascade classifiers for cow detection. The Indian cow has been the biggest obstacle compared to other animals on Indian roads. The distance between a cow and the vehicle is calculated prompting an alert signal to notify the driver for applying brakes. The method is implemented in OpenCV software and tested on various video clips. The proposed system has achieved an accuracy of 80% in terms of cow detection.
