# Hybrid Data Hiding Based on AMBTC Using Enhanced Hamming Code
## 4 Experimental Results
The EC of our proposed method is efficient with respect to the EC as 151,173 bits when \(T=5\). In Table 1, [PERSON] and [PERSON]'s PSNR (=33.0656 dB) is measured as higher than that (=32.6911 dB) of our proposed method. Here, the EC of [PERSON] and [PERSON] [30] is 55,407 bits, and the EC of our method is 151,173 bits. In the end, our proposed method shows the capability to conceal about 95,000 bits more than that of [PERSON] and [PERSON]. If the threshold \(T\) and EC are given for a faithful measurement, the PSNR of our proposed method may be the highest. This is because the size of the hidden bits affects the PSNR. Apparently, a relative good method has high values both for the PSNR and EC. When \(T=10\), we can see that our method's EC (=219,847 bits) is the largest. The method of [PERSON] [33] and our proposed method both have the \begin{table}
