The Internet makes it possible to share and manipulate a vast quantity of information efficiently and effectively, but the rapid and chaotic growth experienced by the Net has generated a poorly organized environment that hinders the sharing and mining of useful data. The need for meaningful web-page classification techniques is therefore becoming an urgent(More)
Analog CNN array computer arises as an alternative to traditional digital processors in many industrial inspection like visual quality control of metal laminates, capable of make in a single chip Tera equivalent operations per second. A 4096 analog CNN processor array is able to perform complex space-time image analysis, being much faster than a(More)
The automatic classification of defective eggs constitutes a fundamental issue of the poultry industry for both economical and sanitary reasons. The early separation of eggs with spots and cracks is a relevant task as the stains can leak while progressing on the conveyor-belts, degrading all the mechanical parts. Present work is focused on the(More)
Present work deals with the automation of a low cost commercial lawnmower to perform unmanned precision agriculture tasks such are the spraying of pesticides. To this aim the vehicle has been endowed with a set of additional subsystems and sensors to perform remote motion control and to obtain relative and absolute location in the field. The equipment(More)
Present work describes the design and implementation of a fuzzy controller for a pneumatic actuator to control the steering of an unmanned lawnmower. The fuzzy controller expresses in natural language the human expertise on the control of this non-linear system by means of a set of linguistic expressions. Few investigations have been addressed to the(More)
In the autonomous piloting of vehicles, the characterization of nearby dynamic object motion by perception and tracking techniques aids in the optimization of avoidance strategies. Knowledge of the features of object motion in goal-driven navigation allows for accurate deviation strategies to be implemented with appropriate anticipation. This perceptual(More)
An image entails a huge amount of data and information. For this reason, image synthesis and analysis by computer systems requires a high processing time. This represents a handicap in systems where real time processing or an immediate interpretation is demanded as in visual inspection industrial applications. Present work, introduces a computer(More)
This work presents two initial approaches and a novel technique for the industrial inspection of residual oxide scale on a cold stainless steel strip. The research aims to develop real-time systems to detect 50-μm defects. Initially, a spectrophotometric analysis provides the wavelength regions where differences between stainless steel and residual oxide(More)
