摘要： A method and apparatus for automatically locating a desired region of interest (ROI) in an original digital image having a plurality of pixel intensity values, comprising:(a) obtaining digital image intensity data representative of an original digital image;(b) sampling the digital image intensity data of the original digital image so as to define a reduced digital image representative of the original digital image;(c) forming an image intensity histogram using the reduced digital image;(d) determining a threshold image intensity value from the histogram as being representative of a minimum image intensity value of a desired ROI;(e) creating a mask image from the reduced digital image, the mask image having image pixels at grid coordinate positions corresponding to similarly positioned pixels in the original digital image, by setting all image pixels in a mask image grid to one of at least a maximum and a minimum intensity value, depending upon a comparison of the threshold intensity value to the image intensity value of a correspondingly positioned pixel in the original digital image; and(f) processing the mask image so as to define at least one contiguous area of pixels in the mask image having a common intensity value, the at least one area comprising the desired ROI.

摘要： Methods of applying tape to a surface. An embodiment of the invention provides a method of applying a tape to a surface, comprising the steps of: providing a tape, wherein the tape includes a tape backing and an adhesive on the tape backing, and wherein the tape is on a liner; cutting the tape to provide a first length of tape, a second length of tape, and a removable portion of the tape located between the first length of tape and the second length of tape wherein a portion of the first end of the removable portion is cut at an angle oblique to the length of the tape; removing the removable portion of the tape from the liner; separating the first length of tape from the liner; and applying the first length of tape to a surface.

摘要： A method for automatically locating a desired region of interest (ROI) in an original digital image involving the use of histograms to determine a threshold that is used to generate a mask to detect the ROIs. Digital image intensity data is obtained and a histogram of the intensity data is formed. The threshold is determined by first determining a histogram point that represents the noise peak in the image intensity data and then setting the threshold to be the image intensity value following the noise peak that first exhibits a positive curvature. The threshold is used to create a mask from the original digital image, and contiguous areas of pixels are defined in the mask. At least one of these contiguous areas is determined to be a desired ROI.
