A Multi-Agents Architecture to Learn Vision Operators and their Parameters
In a vision system, every task needs that the operators to apply should be
{\guillemotleft} well chosen {\guillemotright} and their parameters should be
also {\guillemotleft} well adjusted {\guillemotright}. The diversity of
operators and the multitude of their parameters constitute a big challenge for
users. As it is very difficult to make the {\guillemotleft} right
{\guillemotright} choice, lack of a specific rule, many disadvantages appear
and affect the computation time and especially the quality of results. In this
paper we present a multi-agent architecture to learn the best operators to
apply and their best parameters for a class of images. Our architecture
consists of three types of agents: User Agent, Operator Agent and Parameter
Agent. The User Agent determines the phases of treatment, a library of
operators and the possible values of their parameters. The Operator Agent
constructs all possible combinations of operators and the Parameter Agent, the
core of the architecture, adjusts the parameters of each combination by
treating a large number of images. Through the reinforcement learning
mechanism, our architecture does not consider only the system opportunities but
also the user preferences.Comment: IJCSI, May 201
A New Automatic Method to Adjust Parameters for Object Recognition
To recognize an object in an image, the user must apply a combination of
operators, where each operator has a set of parameters. These parameters must
be well adjusted in order to reach good results. Usually, this adjustment is
made manually by the user. In this paper we propose a new method to automate
the process of parameter adjustment for an object recognition task. Our method
is based on reinforcement learning, we use two types of agents: User Agent that
gives the necessary information and Parameter Agent that adjusts the parameters
of each operator. Due to the nature of reinforcement learning the results do
not depend only on the system characteristics but also on the user favorite
choices
Q-learning optimization in a multi-agents system for image segmentation
To know which operators to apply and in which order, as well as attributing
good values to their parameters is a challenge for users of computer vision.
This paper proposes a solution to this problem as a multi-agent system modeled
according to the Vowel approach and using the Q-learning algorithm to optimize
its choice. An implementation is given to test and validate this method
A Multi-Agents Multi Agents Architecture to Learn Vision Operators and their Parameters
In a vision system, every task needs that the operators to apply should be « well chosen » and their parameters should be also « well adjusted ». The diversity of operators and the multitude of their parameters constitute a big challenge for users. As it is very difficult to make the « right » choice, lack of a specific rule, many disadvantages appear and affect the computation time and especially the quality of results. In this paper we present a multi-agent architecture to learn the best operators to apply and their best parameters for a class of images. Our architecture consists of three types of agents: User Agent, Operator Agent and Parameter Agent. The User Agent determines the phases of treatment, a library of operators and the possible values of their parameters. The Operator Agent constructs all possible combinations of operators and the Parameter Agent, the core of the architecture, adjusts the parameters of each combination by treating a large number of images.
