The microvascularization of the female urethra was studied in fetuses, neonates and infants by injection of agarized China ink into the circulation. The purpose of this study was to specify the angioarchitecture of each tunic and their specific drain

Several optimal techniques exist to reduce speckle effects on polarimetric data, e.g. the Linear Minimum Mean Square Error (LMMSE) vector filter for multilook detected data or optimum summations such as the Polarimetric Whitening Filter (PWF) for one

The authors reported the preliminary results of levator ani muscle flap in the treatment of vesicovaginal fistula.Twenty-six patients whose age varied between 13 and 18 years (mean: 30 years) are selected. All the patients are treated by the vaginal

Segmentation plays a key role in many image processing applications, including SAR image analysis. Given a high quality segmentation, important tasks such as adaptive noise filtering and classification can be greatly simplified. However, the presence

Radar images are inherently degraded by a strong, multiplicative noise known as speckle. The most frequently used speckle filters are adaptive in the sense that the filtering operation depends on estimations of local statistics calculated in a neighb

The LMMSE vector speckle filters for full polarimetric multilook SAR data and for single channel SAR images using pixels's spatial correlation are presented. Both are based on the multiplicative speckle model. In the multilook polarimetric filter, th

Reducing the speckle effects in polarimetric data implies the use of statistical models for the speckle. A well known model is the product model which assumes the same texture variable for all the elements of the covariance matrix (CM). The authors p

For surfaces satisfying the "product model", the sample covariance matrix (CM) is the product of a positive scalar random variable /spl mu/ representing texture and a mean CM representing the polarimetric properties of the surface. The maximum likeli

During the SAREX-92 experiment a first mapping of the mangrove forests of French Guyana was done using SPOT and ERS-1 data. This paper completes this study by using the SPOT, ERS-1 (with 2 more dates), JERS-1, SAREX and AIRSAR-polarimetric data. A mu
