Abstract
An interactive image segmenting apparatus and method are provided. The image segmenting apparatus and corresponding method include a boundary detector, a condition generator, and a boundary modifier. The boundary detector is configured to detect a boundary from an image using an image segmentation process. The feedback receiver is configured to receive information about the detected boundary. The condition generator is configured to generate a constraint for the image segmentation process based on the information. The boundary modifier is configured to modify the detected boundary by applying the generated constraint to the image segmentation process.
Claims18
A medical image segmenting apparatus comprising:
- a display;
- a memory configured to store instructions;
- and
- at least one processor,
- wherein the at least one processor, when executing the stored instructions, is configured to:
- detect a boundary from a medical image,
- control the display to display the detected boundary on the medical image,
- receive one of first feedback information or second feedback information,
- calculate a distance between the displayed boundary and an annotation corresponding to the received one of the first feedback information or the second feedback information,
- divide the displayed boundary into a boundary to be fixed and a boundary to be modified based on the calculated distance, and
- control the display to expand at least one portion of the boundary to be modified based on the received first feedback information, or to reduce the at least one portion of the boundary to be modified based on the received second feedback information,
- wherein the first feedback information comprises at least one of marking a dot outside the displayed boundary, drawing a line outside the displayed boundary, drawing a line starting and ending inside the displayed boundary and passing outside the displayed boundary, or drawing a line starting inside the displayed boundary but ending outside the displayed boundary, and
- wherein the second feedback information comprises at least one of marking a dot inside the displayed boundary, drawing a line inside the displayed boundary, drawing a line starting and ending outside the displayed boundary and passing inside the displayed boundary, or drawing a line starting outside the displayed boundary but ending inside the displayed boundary.
A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed by a computing device, causes the computing device to:
- detect a boundary from a medical image;
- display the detected boundary on the medical image;
- receive one of first feedback information or second feedback information;
- calculate a distance between the displayed boundary and an annotation corresponding to the received one of the first feedback information or the second feedback information;
- divide the displayed boundary into a boundary to be fixed and a boundary to be modified based on the calculated distance;
- and
- expand at least one portion of the boundary to be modified based on the received first feedback information, or reduce the at least one portion of the boundary to be modified based on the received second feedback information,
- wherein the first feedback information comprises at least one of marking a dot outside the displayed boundary, drawing a line outside the displayed boundary, drawing a line starting and ending inside the displayed boundary and passing outside the displayed boundary, or drawing a line starting inside the displayed boundary but ending outside the displayed boundary, expand at least one portion of the displayed boundary, and
- wherein the second feedback information comprises at least one of marking a dot inside the displayed boundary, drawing a line inside the displayed boundary, drawing a line starting and ending outside the displayed boundary and passing inside the displayed boundary, or drawing a line starting outside the displayed boundary but ending inside the displayed boundary, reduce at least one portion the displayed boundary.
