A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw a ...

Real life situations such as travelling over time and across distance can be drawn on a graph. Exact distances and times are plotted on the graph. These are shown as co-ordinates. These points are ...

Abstract: We propose a generalized gradient vector field based two-stage affine snakes method for the segmentation of optic nerve head in retinal fundus images. We obtain the course segmentation using ...
