Compare between steganography and watermarking. 4. Name and describe different types of edge models used for edge detectio The most popular physical genetic transformation method is electroporation. This is due to its quick-ness, low cost, and simplicity even when it has a low efficiency, requires laborious protocols for regeneration after genetic transformation, and can only be applied to protoplasts [1,2,12-15]. Electroporation is based on the application of Log Transformations. The log transformation curve shown in fig. A, is given by the expression, s = c log(1 + r) where c is a constant and it is assumed that r≥0. The shape of the log curve in fig. A tells that this transformation maps a narrow range of low-level grey scale intensities into a wider range of output values
