    摘要： The invention relates to a micromachined accelerometer using a movable seismic mass suspended in relation to the substrate by elastic connections only allowing translation in its own plane along a sensitive axis (Oy). The mass acts on at least one elongate resonator by means of a force amplification structure associated with this resonator. The amplification structure comprises a rigid lever arm, a first end of which is connected to the seismic mass by a connection having, in the plane of the mass, a high stiffness in the direction of the sensitive axis (Oy) and a low stiffness in the perpendicular direction, and a second end is connected to an anchor point on the substrate. The second end of the lever arm is a rigid head piece surrounding the anchor point and connected to this anchor point by a rotational connection about a center of rotation. The resonator has one end fixed to the rigid head piece at a point such that the longitudinal axis of the resonator passes a distance h, small in relation to the length L of the lever arm but nonzero, from the center of rotation of the rotational connection.

    摘要： The method realizes a motion compensated temporal filtering (MCTF), the temporal filtering being replaced by an intra mode coding to obtain at least one low (L) or high (H) frequency picture if the current picture has a level of correlation with a lower previous picture at a threshold, the low frequency pictures obtained (L) being thus scaled to be adapted, at the energy level, to the pictures obtained by motion compensated temporal filtering, and comprises, at the end of analysis:a selection of the pictures obtained by intra coding of a picture of a low decomposition level with the additional condition, for the high frequency pictures, that this picture is derived itself from an intra coding. a calibration of the picture selected by carrying out at least one reverse step of the scaling step. The applications relate to video compression with temporal prediction.

    摘要： The invention relates in particular to a method of tracking an object in a sequence of images, each image comprising pixels with each of which is associated at least one value in a determined representation space, termed the colour space. This method comprises the following steps: segmenting, in the spatial domain, the object in an image of the sequence, termed the reference image, by estimation of its contour; and tracking the contour of the object in the other images of the sequence on the basis of the values associated, in the color space, with the pixels of the object segmented in the reference image.
