In this work we develop a real time system that recognizes occluded green apples within a tree canopy using infra-red and color images in order to achieve automated harvesting. Infra-red provides clues regarding the physical structure and location of the apples based on their temperature (leaves accumulate less heat and radiate faster than apples), while color images provide evidence of circula...

The conceptual and formal structure of quantum mechanics is analysed from the point of view of the dynamics of distinctions, occcuring during the observation process. The Hilbert space formalism is simplified with the help of the concept of closure: closure of an eigenstate under an operator is generalized to the linear closure of a subset of states, and this is further simplified to orthogonal...

cating artery was first described by Robinson and demonstrated on angiography by Isherwood and Dutton, 44 cases have been reported (1, 2). Most cases demonstrate unilateral involvement and only 10 cases of bilateral involvement have been reported out of the 45 cases, including the case described in this report. Although cerebral aneurysms are frequently associated with this congenital anomaly, ...

We describe a general method for calculating the infra-red limit of physical quantities in unitary quantum field theories. Using analyticity of Green functions in a complex scale parameter, the infra-red limit is expressed as a contour integral entirely in the ultra-violet region. The infra-red limit is shown to be the limit of the Borel transform of the physical quantity. The method is illustr...

The case is presented of an 8 1-year-old female coming to our observation after two non radical local excisions of a Merkel cell carcinoma of the sub-mental skin region. After a wide local excision, with en bloc elective bilateral neck dissection, simultaneous reconstruction with an infra-hyoid myocutaneous flap was performed. A brief overview concerning this rare tumour is presented and the su...

This paper presents the results of several large-scale studies of face recognition employing visible light and infra-red (IR) imagery in the context of principal component analysis. We find that in a scenario involving time lapse between gallery and probe, and relatively controlled lighting, (1) PCA-based recognition using visible light images outperforms PCA-based recognition using infra-red i...
