摘要 |
A method and system for identifying existence and occurrence of a contour. The contour presence can be identified by taking a second derivative of a color space (e.g., L*, a*, and b*) value of a rendered image derived utilizing an ICC profile that models behavior of a MFD as a smoothness metric. A moving average filter can be applied to minimize an extraneous peak and trough in the second derivative that can be contributed to noise. The contour can be detected if a filtered second derivative lies outside a given range. The location of the contour can be identified by matching up an input value with corresponding input value of the image. A probability of the contour being visible in a rendered output can be then determined by separately analyzing the color space values. The occurrence and location of contour can be displayed on a user interface to quickly and clearly identify the contour in the image without making physical prints and with minimal human interaction and expenditure. |

1. A method for identifying an existence and an occurrence of a contour, said method comprising:
identifying an occurrence of a contour by taking a second derivative of a color space value associated with an image derived via a color management profile that models a behavior of a multi-function device as a smoothness metric; identifying a location of said contour by matching an input value to a corresponding input value of said image to thereafter determine a probability of said contour being visible in a rendered output thereof by separately analyzing said color space value; presenting said occurrence and said location of said contour to assist in quickly and clearly identifying said contour in said image without rendering a physical print thereof and with minimal human interaction and expenditure; selecting a sweep to analyze and a destination profile to render said image; and displaying said rendered image and a graphical bar emanating from a highest probability contour at an appropriate input value in order to enable quick to toggling between said destination profile and said sweep. |
