Today I wrote a program to generate false color image with a different method .In this method we change the sequence of RGB channels with three methods :
1)BGR - > BRG
2)BGR - > RGB
3) BGR - > GBR
Here are the input & output Images for these operations:-

There are various other color rendering method used which are explained below:-
1)Pseudo Color
2)Density Slicing
3)Chloropleth
1)Pseudo Color:-A pseudo color is derived from a gray scale by mapping each intensity value to a color according to a table or function.Pseudo color is typically used when a single channel data is available while
false color is used when all three channel data is available . A typical example of pseudo color is thermography where infrared cameras feature single spectrum band & show their gray scale images in Pseudo color.Another familiar example of pseudo color is encoding of elevation using hypsometric tints in physical relief maps.Pseudo color makes some details more visible.For adding geographical information,combining information obtained from infrared & ultra violet light or MRI scan.
2)Density Slicing:-Density slicing is a variation of pseudo color .It divides an image into few colored bands
& is used in analysis of remote sensing images .For density slicing ,the range of gray scale divides into interval ,with each interval assigned to one of a few discrete colors. This is a contrast to pseudo colors which uses a continuous color scale.
3)Chloropleth:-Chloropleth is an image or map in which areas are colored or patterned proportionally to the category or value of one or more variables being represented.The variables are mapped to a few colors.
Each area contributes one data point & receives one color from these selected colors.A chloropleth map of geographical area is a extreme form of false color.
Uses Of False Color:- False color is widely used in astronomy & medical science .In Astronomy it is widely used for satellite & space images .It is used in remote satellite .For example,space telescope like hubble space telescope,aircraft like rovers mostly uses the false color for their operations.Weather Satellite also uses false color.
In medical science it has a very useful application .It increase the visibility of some details .In MRI scan this is widely used .
Negative of an Image:-Negative of an image convert brightest part of an image to the darkest part & darkest part to the brightest part.If we substract the each intensity value to 255.Today,I wrote a program to convert a color image & gray scale to their negatives.Here is the input & output Image for this program.
