This article constitutes a contribution to an analysis of the notion of variable. Whithin the framework of Combinatory Logic as a formalism without bound variables, the Logic of Determination of Objects (LDO) provides an explanation for the necessary distinction between " whatever, any " and " indeterminate , indefinite " used by the introduction and… (More)
We propose a rigorous definition of the notion of typicality, making use of the strict partial order naturally induced among the objects at hand by a given concept. This perspective enables us to transpose in the framework of object determination logic some well-known problems like contextual typi-cality or contextual inference. Then these problems can be… (More)
We present a new approach for modeling color attacks of rgb-color watermarked images. We have used a based interpolation watermarking algorithm and supposed that the attacks are simulated by a scaling of the colors followed by a translation. We give bounds for the extracted watermark depending on the original image, the watermark and the attack. Different… (More)

From a logical viewpoint, object is never defined, even by a negative definition. This paper is a theoretical contribution about object using a new constructivist logical approach called Logic of Determination of Objects (LDO) founded on a basic operation, called determination. This new logic takes into account cognitive problems such as the inheritance of… (More)
The study aims to preserve integrity of JPEG bitstream transmitted in Wireless Multimedia Sensor Networks (WMSNs) environment, lightweight complex process that is proposed to parse bitstream of encoded medical image and formulated the encryption process for that represented bit of Diff value in DC coefficients rather than appended bits of ACs coefficients.… (More)
