Crowd counting is a crucial computer vision task with numerous practical applications. Convolutional neural networks (CNNs) are a common foundation for crowd counting. This approach makes use of deep learning to automatically learn attributes from photos that can be used to gauge the crowd size. In order to forecast the density map of a given crowd image, a network is often trained as part of the CNN-based crowd-counting method. The crowd density at each spot in the image is continuously estimated by the density map. The density map is integrated over the full image to produce the final crowd count. The CNN architecture has undergone a number of tweaks and improvements to further demonstrate the method's robustness. In general, CNN-based crowd-counting has yielded positive results and is a viable method for automatic crowd counting in a variety of settings. When employing CNNs to count crowds, there are a number of obstacles that must be overcome. It might be difficult to determine the precise number of individuals present due to crowds' variable densities and sizes. The task might also be made more difficult by occlusions and perspective distortions. Several CNN architectures designed specifically for crowd counting have been developed to address these issues. These architectures frequently include supplementary modules, such as density estimation and multi-scale feature extraction, to boost accuracy.
