I am putting together a computer vision dataset for detection, identification, classification and counting for cattle herds of Indian breeds, which are the strength of Brazilian livestock farming [where there are still a lot of cattle in free-range pastures]. The dataset will also be useful for monitoring illegal livestock farming in protected areas, such as the Amazon. The scarcity of images of these types of cattle on the Internet, where European varieties are prevalent, forces me to negotiate with local farmers to fly my drones in order to obtain the images. It's not an easy job. Most are confrontational and hostile. I move forward with great difficulty but I will not give up. Soon at cownt.com.br.
Edited for clarity.
