Goals / Objectives
Develop a real-time system technology for solving practical problems in the poultry processing industry (This research will be conducted jointly by U.S. and Israel.) Develop a synergetic x-ray and laser range imaging method for sensitive detection of bone fragments and hazardous materials in de-boned poultry meat, which includes the basic theory, experimental verification, and system implementation and analysis. The system is anticipated to be more accurate than human (less than 3% error rate). Specific goals are (1) Develop a digital x-ray system for acqiring x-ray images of de-boned poultry on processing lines (This stage to be conducted at the U.S. site.); (2) Develop a high resolution online 3D imaging system for acquiring thickness or depth of images of de-boned poultry and compensating x-ray false patterns; Convert 3D depth image to virtual x-ray image for thickness compensation (This stage to be conducted at Israel site.); and (3) Develop on-line integrated system for real-time combining x-ray and 3D images; this includes parallel image processing, dynamic acquisition and synchronization between x-ray and stereovision and between mechanics and electronics, and image registration between x-ray and 3D range images. Develop algorithms for sensitively extracting bone fragments and interfacing hardware and software systems, includes system testing and analysis. The synergetic sensing fusion technique will increase the x-ray detection capability for internal imaging and inspection of agricultural products and biomaterials.
Project Methods
Develop a digital x-ray sensing system for acquiring x-ray images of de-boned poultry on processing lines and analyze x-ray absorption characteristics of poultry materials for contrast imaging of meat, calcified / less-calcified bones, fat, and blood clots; and to consider the detection of cartilage (This stage to be conducted at the U.S. site.) Develop a high resolution online 3D imaging system for acquiring thickness or depth images of de-boned poultry and compensating x-ray false patterns; Convert the 3D depth image to virtual x-ray image for thickness compensation. Develop on-line integrated system for real-time combining z-ray and 3D images; this will include parallel image processing, dynamic acquisition and synchronization between x-ray and stereovision and between mechanics and electronics, and image registration between x-ray and 3D range images. Develop algorithms for sensitively extracting bone fragments and interfacing hardware and software systems. Conduct system testing and analysis.

4d Progress report. This final report serves to document research conducted under a Bi- National Agricultural Research Development (BARD) project. Additional details of research can be found in the report for the parent project 1265-42000-008-00D, entitled "Development of Technology for Automated On- Line Inspection of Animal Carcassesses and Plant Produce." Continued efforts have been made to implement the hardware architecture of the x- ray imaging system and the laser stereo imaging system for on-line acquiring poultry images. X-ray and laser imaging detection of bone and hazardous materials in deboned poultry were integrated. Specifically, research achievements include 1) Established on-line dynamic x-ray imaging system, developed multi-tasking real-time control algorithms and software. The hardware has been under the control of software which established the foundation for further integration steps. 2) Had breakthrough in an on-line real-time pixel registration of fillet images. This is essential for the image processing of object data flow. 3) Further, had enabled concurrent sensor imaging acquisitions and image processing while the conveyer is running, achieved real-time imaging and processing.

    4. What were the most significant accomplishments this past year? This report serves to document the research efforts under a Reimbursable Agreement with the University of Maryland, College Park, with Prof. Yang Tao as Principal Investigator. Additional details of research can be found in the report for the parent project 1265-42000-008-00D "Development of Technology for Automated On-Line Inspection of Animal Carcasses and Plant Produce." During this year, efforts have been made to implement the hardware architecture of the x-ray imaging system and the laser stereo imaging system for on-line acquisition of poultry images. Special research achievements include establishment of an on-line dynamic x-ray imaging system and development of multi-tasking real-time control algorithms and software. These include integration of hardware and software, on-line real-time pixel registration of fillet images, and concurrent sensor and image data acquisitions and image processing to achieve real-time operation.
