## Return on investment (ROI)

Generally, book income as a proportion of net book value.

## Return on Investment

The money that a person or company earns as a percentage of the total value of his/her/its assets that are invested. It is calculated thusly:

Return on investment = (Income - Cost) / Cost

Because it is easy to calculate the return on investment, it is a relatively popular measure of the profitability on an investment and can help in making investment decisions.

## return on investment (ROI)

A measure of the net income a firm's management is able to earn with the its total assets. Return on investment is calculated by dividing net profits after taxes by total assets. Also called rate of return, return on assets. Compare profitability ratio.

## Return on investment.

Your return on investment (ROI) is the profit you make on the sale of a security or other asset divided by the amount of your investment, expressed as an annual percentage rate.

For example, if you invested \$5,000 and the investment was worth \$7,500 after two years, your annual return on investment would be 25%. To get that result, you divide the \$2,500 gain by your \$5,000 investment, and then divide the 50% gain by 2.

Return on investment includes all the income you earn on the investment as well as any profit that results from selling the investment. It can be negative as well as positive if the sale price plus any income is lower than the purchase price.

## return on investment (ROI)

A generic term to define a number of analytical tools for measuring the financial benefits of an investment, including cash-on-cash, internal rate of return, equity dividend,and financial management rate of return.

Second, these ROI and BG bitplanes belonged to GB are up-shifted over the top of the maximum ROI bitplane in LB.
Third, the most significant ROI and BG bitplanes are up-shifted to the higher position than the maximum bitplane in GB.
1]: The bitplane number in MB region belonged to ROI coefficients;
3]: The bitplane number in GB region belonged to ROI or BG coefficients;
4]: The bitplane number in LB region belonged to ROI coefficients;
At the decoder, for any given non-zero wavelet coefficient, the first step is to identify whether it is a bitplane of the ROI coefficient or the BG coefficient.
5], then b [member of] ROI and b [member of] MB, shift it down to bitplane b - [S.
5], then b [member of] GB, but b [member of] ROI or b [member of] BG, shift it down to bitplane b - [S.
5], then b [member of] LB and ROI, shift it down to bitplane b - [S.
In JPEG2000, both Maxshift method and the general scaling based method can support the multiple ROI coding.
Second, it does not have the flexibility to allow for an arbitrary scaling value to define the degree of relative importance between the ROI and the BG wavelet coefficients.
Since it is not necessary for the GLBShift method to code and transmit the shape information of every ROI, the complexity of the proposed algorithm is less and coding efficiency is higher than the general scaling based method for the same image.
