1D Describing the shape of stem plots and histograms Symmetric distributions The data shown in the histogram shown below can be described as symmetric. There is a single peak and the data trail off on both sides of this peak in roughly the same fashion. Histogram is considered as a graph or plot which is related to frequency of pixels in an Gray Scale Image with pixel values (ranging from 0 to 255). Grayscale image is an image in which the value of each pixel is a single sample, that is, it carries only intensity information where pixel value varies from 0 to 255.The standard backprojection called by calcBackProject 2)I am using images retrieved directly from the camera.
