because in fractal coding you save Coefficients of image blocks instead of values of block pixels. decoding starts from initial image and Coefficients applied on it. so the initial image can have any resolution

Why you are gotng to image compression?
image compression makes the image smaller in order to fit a desired size. you literally compress the image and make it smaller in bit size.
Are resolution definition and sharpness of an image are all components of?
MAGNIFICATION
What is the image resolution of screen based images?
The screen based images should have the same resolution as the screen - usually about 72dpi.
What is image acquisition in digital image processing?
It is the creation of digital image, typically from a physical scene. The term assumed to imply or include processing,compression, storage, printing, and display of such image.
What is the relationship between pixel to pixel in image processing?
Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
How resolution and colour depth affect file size and image quality?
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
Measure of clarity of an image?
For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image. In effect, spatial resolution refers to the number of independent pixel values per unit length.
What has the author Uwe Strohbeck written?
Uwe Strohbeck has written: 'A new approach in image data compression by multiple resolution frame-processing'
What causes low resolution?
Low resolution is usually caused by a poor compression rather than poor capture. Low resolution images have less physical pixels than a high resolution one. The stretching of the image is what causes them to look poor. This low number of pixels is usually the result of downsampling of the the image for email or file size purposes.
What is special characteristic of koch snowflake?
It is a fractal: each enlargement of the snowflake is an identical image.
How to calculate Compression ratio for an image?
compression ratio=uncompressed image size/compressed size
What is the need for compression?
motivation of lossless image compression
What happens to resolution when image is maginfied to 400x?
with your image resolution? Nothing happens it remains the same till you change it in Image Size dialog. Image > Image Size.. Magnification is for your convenience to see enlarged image nothing really happens to actual resolution of original image.
Why you are gotng to image compression?

How do you decrease the size of JPEG pictures so that you can send them for example by lowering the resolution?
Go to Image > Image Size. If you want to keep current Width and Height of the image uncheck Resample image then type new reolution in Resolution field. When you want to resample image (to change Width and Height to match new resolution) check Resample Image and type desired resolution in Resolution field.
What determines the resolution of a digital images?
Resolution of image is used to determine the quality of image in digital camera.
How do you work out the resolution of an image?
Right click the image, choose properties and go to the summary tab. You will find there the image width and height. Together they give the image resolution.
