“…In general, thresholding algorithms do not use spatial information of an image and they usually fail to segment objects with low contrast or noisy images with varying background. [13] The simplest method of image segmentation is called the thresholding method. This method is based on a clip-level (or a threshold value) to turn a gray-scale image into a binary image.…”

“…Most of the existing thresholding methods are bi-level, which use two levels to categorize the image into background and object segments. It can extract the object from the background by grouping the intensity according to the threshold [1]. The watershed segmentation is a process of image classification; it is first used by Beucher [2].…”

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.

“…the K-mean is a cluster analysis. It depend on partition (n) observer into K cluster with minimum distance and nearest mean) [13][14] . In KM algorithm, the classification depend on the measurement of the distance from the classes to cluster centroids every pixel is assigned to its closest cluster.…”

“…This produces a separation of the objects into groups from which the metric to be minimized can be calculated. [14] The grouping is done by minimizing the sum of squares of distances between data using Euclidean distance formula and the corresponding cluster centroid. In statistics and data mining, k-means clustering is a method of cluster analysis which aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean.…”

Automatic segmentation of brain tumor using computer analysis aided diagnosis in clinical practice but it is still a challenging task, especially when there are lesions needing to be outlined. In the applications of image-based diagnosis and computer-aided lesion detection, image segmentation is an important procedure .Features extracted from image analysis in companion with image segmentation algorithms are used to provide region-based information for clinical evaluation procedures. Brain tumor diagnosis is easy by using these medical equipments. The physician needs the correct measurement of the tumor area for the further treatment, this need to extract the abnormal part from the 2D MRI scan accurately and measure the region of interest. The HumanComputer interaction is helpful for this procedure. In this search the wavelet transformation is used as well as the Kmean algorithm is used. the wavelet transformation is not sufficient to produce a good result for the brain tumor detection. so the K-mean clustering method with different classes gives best result.
