             abstract = "The problem of extracting features in digital images has been, for 
                         a long time, a very large challenge in various areas of 
                         engineering. For example, Kovalevskii (1967) used the dynamic 
                         programming algorithm to extract tipografados characters and 
                         manuscripts. The use of small format digital cameras aboard 
                         unmanned aerial vehicles UAV is a popular option for the mapping 
                         of tree plantations as a tool for forest management. This article 
                         describes a comparative study of two methods for counting trees in 
                         mosaics of photographs obtained by VANT. The first method is the 
                         well-known classification supervised and the second is a method 
                         based on segmentation and classification of segments after the 
                         image be transformed to a most advantageous color system that 
                         allows the derivation of an index of vegetation. The results show 
                         that both methods are capable of producing equivalent results, but 
                         the method of segmentation is faster and easy to apply. The 
                         results presented by both methods show that the methods used are 
                         not totally accurate, but rather tools for an estimate close to 
                         reality. In general the methods pose a good estimate for the 
                         solution of the problem, and can the undertaking in question 
                         employ both. With that concluded that the results are 
                         satisfactory.",
