Computational Complexity Evaluation The added calculation in the sampling rate and quantization bit-depth optimization comes from three processes, namely feature extraction, the optimal bit-depth prediction, and the sampling rate estimation. 2 In function extraction, the additional calculation mainly comes from 0 , y0 , f max (y0 ), f min (y0 ), BD , BD , H0,bit=4 on the measurements with sampling rate m0 . The number of measure-Entropy 2021, 23,13 ofments is m0 N 2 . We assume that the calculation of one particular subtraction is equivalent to that of 1 addition. The calculation of y0 requires m0 N two – 1 additions and a single multiplication. 2 The calculation of 0 desires m0 N two 2 – 1 additions and m0 N two +1 multiplications. f max (y0 ) and f min (y0 ) will need m0 N 2 -1 2 judgment operations. The calculation of block errors requirements m0 ( N 2 – B2 ) additions. BD desires m0 ( N two – B2 ) – 1 additions and one multiplication. BD desires m0 ( N 2 – B2 ) two – 1 additions and m0 ( N 2 – B2 )+1 multiplications. The additional calculation of H0,bit=4 comes from quantization with bit-depth four, which demands m0 N 2 multiplications. The remaining calculation of H0,bit=4 mainly comes from counting the amount of symbols and calculating the entropy. The calculation of counting the amount of symbols requires m0 N two judgments, m0 N two additions. As the maximum quantity of symbols is 24+1 + 1 = 33, the calculation of entropy requirements 66 multiplications, 33 logarithms, and 33 additions in the most. Within the optimal bit-depth prediction, the calculation mostly comes in the neural network model. You will find seven neurons within the input layer, two neurons in the output layer, 4 neurons in the 1st hidden layer, and 3 neurons in the second hidden layer. When the activation function just isn’t regarded as, the calculation with the network involves 7 four + four three + three 2 = 46 multiplications and six 4 + four + 3 three + three + two two + 2 = 46 additions. Within the sampling rate estimation, the volume of calculation mostly comes in the calculation of (25) and (26). Compared with the 3-Chloro-5-hydroxybenzoic acid medchemexpress computations of your CS measurements, a fixed quantity of operations is usually ignored. The extra calculation involves m0 N two eight additions, m0 N 2 three multiplications, and m0 N 2 3 judgments. Assuming that two additions are necessary for 1 judgment operation, the total level of further computation needs m0 N 2 14 additions and m0 N two three multiplications. The computations of all CS measurements needs m N two B2 multiplications and m N two (B2 – 1) additions. B may be the size with the image block, which is a minimum of 16. When B = 16, the optimization procedure demands to boost 3/B2 (m0 /m) 3/256 1.17 multiplications and 14/(B two – 1) (m0 /m) 14/255 5.49 additions. In pc operations, the quantity of calculation of addition is at the least ten occasions faster than multiplication. The computations of rate-distortion optimization won’t exceed two from the computations on the partial measurements. Moreover, using the raise of image block size or sampling rate m, the percentage of computation in the optimization process will be additional lowered. six.
