Pixel

"Pixel is not a small Square"

A Pixel is not a Square:

A pixel isn't a small square and actually a point sample. It exists only at a point. For a colour picture, a pixel might actually contain three samples, one for each primary colour contributing to the picture at a sampling point.

Picture Resolution:

The Quality of a digital picture is largely dependent upon the number and size of the digital camera
pixels contained in the image

The Picture resolution is when the images are original then turned to a size which will increase or decrease the amount of pixels used.

This image shows the quality of the same image changing because of the resolution.

Image Resolution:

Image resolutions refers to the amount of digital information contained in an image file. A image that
has more pixels will have a higher resolution. Higher resolution pictures will be sharper, clearer, and more pixels in the image.

This image shows that the higher the amount of pixels the better the quality

Intensity: 

Intensity is another word for value. its the value of the pixel within the image. The higher the intensity the higher the quality of the image. Simple 8-bit integers or vectors of 8-bit integers are the 

most common sorts of pixel values used. Some different formats support different formats which can

be 32-bit integers or floating point values Such values are extremely useful in images processing as they allow processing to be carried out on the image where the resulting pixel values are not necessarily

Picture Element:

A picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element or a picture represented on the screen. Its the smallest resolvable rectangular area of an image, either on a screen or stored in memory.
