scope11

Infancy stage

Systems: successful under constrained

conditions for specific applications

Most of the systems 2D and monochromatic

Needs 3D systems with colour processing

More robust, humanlike (artificial intelligence)

Developing generic image processing systems

that can be used for multiple applications may

increase acceptability.

Conclusion12

Due to advances in electronics and computer technologies, vision systems can be installed in almost all food plants for an effective quality evaluation/control operation.

One of the biggest barriers in applying machine vision to the food processing industry is the system cost.

Though the system cost for image processing system has been significantly reduced the ratio of cost to benefit is still unacceptable in many potential applications.
