The proposed SBG-DIR framework is general and can be used for 2D and 3D case. The performance of the proposed SBG-DIR model has been validated on the clinical follow-up CT volume pairs after pre-processing from eight lung cancer patients, who received several follow-up CT examinations. Each examination was performed at intervals of 6–12 months using the same scanner and scan protocol from the Guangdong General Hospital. The number of slices per CT scan ranges from 273 to 360 with a slice thickness of 1.25 mm and each slice image is 512 × 512 pixels at a resolution ranging from 0.64 to 0.88 mm per pixel. The proposed SBG-DIR method is implemented in MATLAB and open functions in C++. The program is tested on a HP-2008 workstation with 64-bit Windows 7 OS, CPU Intel Xeon(R) X5690 (3.47 GHz), RAM 192 GB DDR3 1333 MHz and graphics card NVIDIA Quadro 6000 with 4GB video memory.
A Fast Image Encryption Algorithm Based on Convolution Operation
Published in IETE Journal of Research, 2019
The computer used is configured with Intel(R) Core(TM) i7-4720HQ [email protected] GHz, 8 GB DDR3 RAM, Windows 10(64-bit), MATLAB 9.0 and Eclipse C/C++ with MinGW GCC Tool Chain. The images used in the test are Lena, Baboon, Pepper, all-black and all-white images all of size 512 × 512, as shown in Figure 4(a–e). Without loss of generality, the simulation uses the secret key K = {989209, 340466, 336436, 110955, 421653, 100976, 24776, 527877, 201612, 865082, 563081, 647203, 163613, 794037, 462583}. With the image cryptosystem shown in Figure 3, the plain images as shown in Figure 4(a–e) are encrypted into the cipher images, as shown in Figure 4(f–j), respectively, and the cipher images in Figure 4(f–j) are decrypted into the original images, as shown in Figure 4(k–o), respectively.
