Hepatic CT image query based on threshold-based classification scheme with gabor features
Hepatic computed tomography (CT) images with Gabor function were analyzed. Then a threshold-based classification scheme was proposed using Gabor features and proceeded with the retrieval of the hepatic CT imag...
