Machine vision has been successfully used for mechanical destruction of weeds between rows of crops. Knowledge of the position of the rows where crops should be growing and the assumption that plants growing outside such positions are weeds may be used in such systems. However for many horticultural crops, the automatic removal of weeds from inside a row or… (More)
In the context of texture classification, this article explores the capacity and the performance of some combinations of feature extraction, linear and nonlinear dimensionality reduction techniques and several kinds of classification methods. The performances are evaluated and compared in term of classification error. In order to test our texture… (More)
Freedom of the manducatory apparatus is critical to economical and accurate vocal production. Two types of dysfunction will be discussed: global muscular hypertonia of the muscular manducatory system and dysfunction of the temporomandibular joint (TMJ). Hypertonia occurs in a high number of dysphonic patients. It impairs mandibular mobility and also induces… (More)
The hominisation of the skull comes with the bipedic posture, due to a network of muscular and aponevrotic forces applied to the cranio-facial skeleton. A brief sight of the morphogenetic origine and issues of these forces help to understand more clearly the postural statement of the larynx, his functions, and his many extrinsic biomechanical bounds; then… (More)
The speech therapists work on voice rehabilitation, with different kinds of formation. The dysfunctions of the vocal gesture may have various causes, and manual therapy is some time usefull to correct them. A study shows that using manual therapy is already effective after 10 voice sessions.
The authors summarise a study carried out in the University Hospital of Liège which attempts to correlate vocal cord pathology, posture, and the concept of muscular chains. They have hoped to develop the concept that a postural disorder may be the origin of demonstrable asymmetrical vocal cord disorders. Could there be a bilateral causal relationship… (More)
