14 p, 181.4 KB A general procedure of estimating the population mean in the presence of non-response under double sampling using auxiliary information / Singh, Housila P. ; Kumar , Sunil
In the present study, we propose a general class of estimators for population mean of the study variable in the presence of non-response using auxiliary information under double sampling. The expression of mean squared error (MSE) of the proposed class of estimators is derived under double (two-stage) sampling. [...]

In this paper, a novel framework is presented to recover the 3D shape information of a complex surface using its texture-less stereo images. First a linear and generalized Lambertian model is proposed to obtain the depth information by shape from shading (SfS) using an image from stereo pair. [...]
