Textural analysis of liver tumor using watershed segmentation based on statistical and geometrical features

Abstract EN

The liver diseases can define as the tumor or disorder that can affect the liver and causes deformation in its shape.

The early detection and diagnose of the tumor using CT medical images, helps the detector to specify the tumor perfectly.

This search aims to detect and classify the liver tumor depending on the use of a computer (image processing and textural analysis) helps in getting an accurate diagnosis.

The methods which are used in this search depend on creating a binary mask used to separate the liver from the origins of the other in the CT images.

The threshold has been used as an early segmentation.

A Process, the watershed process is used as a classification technique to isolate the tumor which is cancer and cyst.

The test images are taking five for cancer case and five for the cyst, the geometrical and statistical features are calculated for both cases to identify the identity for each case.

The statistical features are obtained from the gray level co-occurrence matrix which is contrast, homogeneity, correlation and energy.

The geometrical features are the area of the tumor, the circumference and irregularity.

The irregularity tends to lose one of the cyst cases than for cancer because of its shape in more regular than cancer.
