Shape Recovery of Book Surface Using Two Shade Images Under Perspective Condition

Shape Recovery of Book Surface Using Two Shade Images Under Perspective Condition

A shape recovery problem of book surface using two shade images under the fully perspective environments is discussed. In order to simplify the problem, the whole recovery process is divided into three sequential and explicit steps: preprocessing, apparent shape recovery, and generation of ortho-image. The separation of albedo and shading with reduced e ect of interre ections is done in preproc...

Cervical surface shape recovery using digital imaging colposcopy

A common application of digital imaging colposcopy in cervical examinations is the measurement of lesion dimensions and areas. Typically this is done by interactively marking the region of interest on a cervix image, calculating the corresponding pixel dimensions and then scaling to the colposcope optics. Until now no one has suggested a solution to the effects of the cervical surface slant on ...
