Return on investment

(ROI)
An economic indicator that is used to evaluate the effectiveness of an investment. It is calculated as the ratio of the amount gained or lost relative to the amount invested. Simple ROI analyses do not take the time value of money into account; dynamic ROI analyses recognize that the value of money changes over time.

1(a), the general scaling based method can place ROI associated bits in the higher bitplanes by downshifting the bits of BG coefficients from Most Significant Bitplane (MSB) to Least Significant Bitplane (LSB), so that ROI coefficients can be coded firstly after the wavelet transform.
* Second, if arbitrary ROI sharps are desired, the shape coding will consume a large number of bits, which significantly decreases the overall coding efficiency.
So the current standard restricts ROI shape to be rectangle and ellipse [2].
In other words, it is a particular case of the general scaling-based method when the scaling value is so large that there is no overlapping between BG and ROI bitplanes.
In that case, all significant bits associated with the ROI coefficients after scaling will be in higher bitplanes than all the significant bits associated with the BG coefficients.
Five major limitations of Maxshift method for ROI coding are as follows [10]-[12].
There is no formula to express this risk of incarceration ROI, nor is there a formula that adequately expresses the cost of personal imprisonment.
However, the main focus for ROI has to be on building a business case that justifies the investment of staff, time, and money through the returns of profits, reduced expenses, streamlined processes, increased revenues, and/or augmented productivity.
The creation of a successful ROI case depends on careful attention to detail.
A primary component of any ROI case is a statement of the scope of the argument.
* Technology that is a part of the ROI case and that is not included in the analysis
The financial measures that will be used to calculate the financial impact of the investment are essential components of every ROI case.
