What are the main problems of steganography?
The biggest problem steganography faces is that of size. There is a limit to the size of a file which you can embed information into. For instance if you take a 16 bit image where each pixel is 4 bytes in three colours RGB you can only reliable encode the lower byte before the colour changes become visible in the viewed image. This means that the image you are embedding your data in has to be 1 quarter larger than the encrypted data itself.
How does compression effect images?
Any type of compression will ideally reduce the size of an image. There are two types of compression which describe how they affect images:"Lossy" compressionThis type of compression reduces the size of the image by removing some data from it. This generally cause, effect the quality of the image, which mean it will reduce your image quality."Lossless" compressionThis type of compression reduces the size of the image by changing the way in which the data is stored. Therefore this type of compression will make no changes in your image.
What is a computer image?
It is an image on your computer.
How do you put an image from your documents you dont have or know image urland is not in wiki's data and you want to use that pic?
If you can get the image on your computer screen, try using Screen dash. You can then capture the image of your screen then edit the photo, save the image, or image host it.
Where are visible lines used?
visible lines are the part of clipping of object in computer graphics. if you find out the line in the figure area then this line is said to be visible line
How is Christ the image of the invisible God?

What layer is visible when viewing an image of the sun.?

A disadvantage of a visible satellite image is that it cannot be used at night?
Yes that is the primary disadvantage of visible satellite imagery.
What is meant by the term pixelation?
"Pixelated" is when an image is made up of tiny visible pixel images. It can also mean that an image has been converted from a printed image to a digitized image.
What lens that magnifies the image before reaching your eye?
retina is the part in eye which inverts the image visible to us and then magnifies it.
What produces an image of a specimen by passing visible light through it?
Its a Light Microscope! (=
How many bands of light does a landsat image have?
It has 7 bands, only 3 of which are in the visible.
How much is a quarter that is so off center that you can't tell the date?
The value of an off-center strike depends on how much of the coin's full image is visible: 80% visible - roughly $5 60% visible - $30 10% visible - $100
In relation to a microscopewhat is magnification and resolution?
Magnification is the amount by which the image you see will be larger than the actual object, ie. if the image you see appears to be twice as large as the original object then it will be a 2x magnification. (magnification = size of image / size of object) Resolution is the smallest possible visible thing on the enlarged image. On a satellite picture the resolution may be 1m2 meaning that anything smaller is not visible on that picture. In the case of an electron microscope, for example, anything smaller than 1 electron will not be visible using the electron microscope.
How could you demonstrate that an image as indeed a real image?
Real images can be produced on a plane and they would be inverted. You can demonstrate that a real image is there by placing a piece of thin tissue there, or blowing smoke through the area. In either case, the image will become visible.
What part of an image intensification tube converts the X-ray image into a visible image?
Input Phosphor. The x-ray image intensifier converts the transmitted x rays into a brightened, visible light image. Within an image intensifier, the input phosphor converts the x-ray photons to light photons, which are then converted to photoelectrons within the photocathode. The electrons are accelerated and focused by a series of electrodes striking the output phosphor, which converts the accelerated electrons into light photons that may be captured by various imaging devices.
What is cameltoe?
