The prevalence of psychiatric morbidity in patients with pulmonary tuberculosis is significantly high. Depressive Neurosis is the commonest among them. The psychiatric morbidity is related to the duration of illness, the degree of incapacitation and the knowledge of sputum AFB positive status.

The orientation correlation function is a measure of the spatial range over which nanoscale structures maintain their structural (orientational) similarity. In this paper we describe an image processing system that is used to estimate this correlation function from electron microscope images of the chemically patterned nanoscale structures. We describe the(More)
We present a novel algorithm to extract height ordering information for points relative to the ground plane. The ordering of scene points is obtained by exploiting the idea of linearly invariant representation of space points, image points, and the optical center of the camera , from which we derive a measure that is mono-tonic with respect to the height of(More)
