Video Data Hiding Using Forbidden Zone Data Hiding and Selective Embedding Ersin Esen and A. Aydin Alatan‚ Member‚ IEEE Abstract—Video data hiding is still an important research topic due to the design complexities involved. We propose a new video data hiding method that makes use of erasure correction capa- bility of repeat accumulate codes and superiority of forbidden zone data hiding. Selective embedding is utilized in the proposed method to determine host

Elasticity is a measure of responsiveness. It shows us how much something changes when there is another change in one of the other variables that determines it. There are three elasticities of demand that we consider‚ price elasticity of demand (PED)‚ income elasticity of demand (YED) and cross elasticity of demand (XED). An important aspect of a product’s demand curve is how much the quantity demanded changes when price is changed. The economic measure of this response in the price elasticity
