The goal of this paper is to present the results of a study run over 7 consecutive years which aims at characterising the Temporal Stability of Within-Field Variability (TSWFV) for the most routinely...
Is it possible to assess the spatial variability of vine water status ? (2008)
Acevedo-Opazo, C., Tisseyre, B., Guillaume, S., Ojeda, H., Ortega-Faria, S.
Plant water status monitoring during the vineyard growth cycle constitutes a basic parameter for both harvest quality and vineyard management. Unfortunately, the plant water status measurement...
Paoli, J.N., Strauss, O., Tisseyre, B., Roger, J.M., Guillaume, S.
This article deals with a method used to describe and manage spatial knowledge. Each spatial datum is considered as an information element, whose location and value are independently described. The...
Precision viticulture data analysis using fuzzy inference systems (2007)
Grelier, M., Guillaume, S., Tisseyre, B., Scholasch, T.
Various types of data are likely to be used in a precision viticulture framework, to adjust management actions according to within field variations. This paper proposes the use of a fuzzy inference...
Utilisation d'un variogramme flou dans une méthode d'agrégation sémantique (2006)
Paoli, J.N., Strauss, O., Tisseyre, B., Lagacherie, P.
This work deals with spatial interpolation and problems related to the imprecision and the uncertainty of the data. Previous works led us to define a semantic-based aggregation process, which allows...

Research on fog drop interception by top layer rice plant during pesticide spraying provides technical data for the optimum design, performance improvements and correct use of the sprayer. A solution...
Gaudin, J.M., Rabatel, G., Tisseyre, B.
This paper presents a positioning method based on a linear differential processing of pseudo-ranges raw GPS data. This method offers the advantage, compared to a standard differential GPS system...
Study on the quality of pesticide spraying distribution based on DGPS technology (2001)
Hong, T., Tisseyre, B., Sinfort, C., Sevila, F.
A solution of rhodamine B dye and water instead of pesticide was used to spray vine trees located using DGPS technologies. Samples of cotton fabrics positioned vertically and horizontally before and...
Hong, T., Sinfort, C., Tisseyre, B., Sevila, F.
Vines were located by using DGPS technology and sprayed with a solution mixed with water and Rhodamine-B instead of pesticide by air-diffusion sprayer. The Vine Leaf Samples in height and depth...
Image analysis for pruning long wood grape vines (1997)
McFarlane, N. J. B., Tisseyre, B., Sinfort, C., Tillett, R.D., Sevila, F.
Image analysis algorithms were developed for making measurements relevant to the winter pruning of long wood grape vines, and were tested on 60 images. The measurements required were, for each...
Tisseyre, B., McFarlane, N.J.B., Sinfort, C., Tillet, R.D., Sevila, F., Carbonneau, A.
Section I of this article presents the agronomic and technical purposes involved in vine pruning and the decision model used to simulate the pruner's reasoning (fuzzy multicriteria decision making)....
Fuzzy reasoning for long cane pruning (1995)
Tisseyre, B., Sinfort, C., Sevila, F., Carbonneau, A.
Long cane pruning cannot be performed with actual machines which do not allow the selection and the saving of the desired wood. A research is being conducted to design a system enabling such an...
Grape inspection by machine vision (1995)
Tisseyre, B., Sinfort, C., Rabatel, G., Sevila, F.
There is no mean except machine vision to objectively inspect grape visual features like general shape fruit (trapezoidal, cylindrical) and compactness. Other measurements like berry size and...
