Abstract
Methods disclosed permit the outlining of difference images associated with an image pair. In some embodiments, an outlined difference image may be generated by selecting at least one non-zero pixel in a thresholded difference image and setting the value of the selected pixel to the maximum value permitted for that color space. In some embodiments, each color component of the selected pixel may be set to the maximum value permitted for that color component. The outlined difference image may also be scaled while preserving thresholded difference information. In some embodiments, the outlined difference image may be rendered using a monitor or a printer.
Claims21
A processor-implemented method for outlining image differences in an input difference image specified in a color space, the method comprising the steps of:
- selecting at least one pixel in the input difference image, wherein a value associated with the selected pixel exceeds a threshold value;
- and
- generating an outlined difference image by setting the value associated with the at least one selected pixel to a maximum value permitted by the color space.
A computer-readable medium that stores instructions, which when executed by a processor perform steps in a method for outlining image differences in an input difference image, the steps comprising:
- selecting at least one pixel in the input difference image, wherein a value associated with the selected pixel exceeds a threshold value;
- and
- generating an outlined difference image by setting the value associated with the at least one selected pixel to a maximum value permitted by the color space.
A computer-readable memory that stores instructions, which when executed by a processor perform steps in a method for outlining image differences in an input difference image, the steps comprising:
- selecting at least one pixel in the input difference image, wherein a value associated with the selected pixel exceeds a threshold value;
- and
- generating an outlined difference image by setting the value associated with the at least one selected pixel to a maximum value permitted by the color space.
