Vision plays a significant role for human beings by permitting them to communicate with their surroundings in an effective and efficient way. The major aim of machine vision is to bestow artificial systems with enough efficiency to manage without prior predetermined conditions. For this conclusion, the computing constraints of the hosting architectures and the particulars of the tasks to be performed have to be taken into consideration, along with constant adapting and optimizing of the visual processing techniques. However, by exploiting the low cost computational power of off-the-shell computing devices, machine vision is not restricted to industrial environments, where conditions and tasks are made easy and specific, but it is now pervasive to support system solutions of everyday life difficulties.
