The distance transform has found many applications in image analysis. Chamfer distance transforms are a class of discrete algorithms that offer a good approximation to the desired Euclidean distance transform at a lower computational cost. They can also give integer-valued distances that are more suitable for several digital image processing tasks. The(More)
This paper presents an overview of selected topics from an emerging new image analysis methodology that starts from continuous models provided by partial differential equations (PDEs) and proceeds with discrete processing of the image data via the numerical implementation of these PDEs on some discrete grid. We briefly discuss basic ideas, examples,(More)
This paper presents comparative study of a new type of manometer called concentric tube bulb (C.T.B) manometer. Its performance of measuring differential height is studied against conventional U-shaped manometer. Pressure drops and mass flow rates are calculated by taking various systems comprising of different flow measuring devices such as orifice and(More)
