Abstract: Methods, apparatuses, and computer program products are provided for determining a modulation transfer function of an imaging system. A method may include accessing an image of a phantom having a substantially circular shaped feature captured by the imaging system. The method may further include detecting the circular shaped feature within the image. The method may additionally include defining at least one line extending from a point within the detected circular shaped feature to a point outside of the circular shaped feature. The method may also include determining an edge spread function based at least in part on the defined at least one line. The method may further include determining the modulation transfer function of the imaging system based at least in part on the determined edge spread function. Corresponding apparatuses and computer program products are also provided.

Abstract: Methods, apparatuses, and computer program products are provided for controlling luminance of non-tissue objects within an image. A method may include determining one or more seed pixel values for an image. The method may further include determining, based at least in part on the one or more seed pixel values, one or more regions of the image that include non-tissue objects. The method may additionally include defining a mask comprising the determined one or more regions of the image. The method may also include calculating a mask pixel value based at least in part on a defined luminance value. The method may further include setting pixel values within the mask to the calculated mask pixel value. The method may additionally include causing masking of the image with the mask. Corresponding apparatuses and computer program products are also provided.

Abstract: Methods, apparatuses, and computer program products are provided for identifying a region of interest within a mammogram image. A method may include applying a clustering algorithm to a histogram of the mammogram image to identify a predefined number of threshold values. The method may further include determining a predefined number of seed values based at least in part on the identified threshold values. The method may additionally include generating a kernel image for each of the seed values. The method may also include using the generated kernel images to identify a region of interest including a breast within the mammogram image. Corresponding apparatuses and computer program products are also provided.

Abstract: An apparatus is provided that includes a processor and memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform a number of operations. The apparatus is caused to receive a digital image including pixels each of which has a pixel value that has been calibrated according to a first calibration function for calibrating an image for display by a first monitor. The apparatus is caused to transform the pixel value of each of at least some of the pixels to a corresponding transformed pixel value calibrated according to a second calibration function for calibrating an image for display by a second monitor. The apparatus is also caused to cause output of the digital image including the plurality of pixels each of at least some of which has a transformed pixel value, the respective digital image being displayable by the second monitor.
