A MATLAB function creation

by | Mar 13, 2021 | Programming

Create and Implement a function named rgb26cc() in MATLAB to convert any given RGB color image to corresponding 6-bit color coded image. The function will take an RGB color image as its input. The function should convert RGB values of each pixel in the input to the corresponding 6-bit color code.

Questions

  1. Create a MATLAB function named rgb26cc(), which takes one input parameter:

(1) imRGB (an RGB color image)
The rgb26cc() function should return a 6-bit color coded image matrix named im6CC with the same height and width

of the original RGB color image.

Implement RGB to 6-bit color code conversion according to the procedure introduced in the class. Please notice that the procedure converts only one pixel at a time, and thus, you must do one of the following ways for converting the entire image.
Intuitive Version
Create a nested loop to read RGB values for each pixel in imRGB and convert the RGB values to corresponding 6-bit color code. Create a new matrix of the same height and width and write the 6-bit color code to the corresponding location in the new matrix im6CC. The intuitive version is easy to understand but will be extremely slow when processing a large image.
High-Performance Version
Handle the conversion using matrix operation, which do not need a nested loop to process individual pixel. The high-performance version can convert the entire image with few statements. You will need to have comprehensive understanding to develop the algorithm. You will earn extra bonus points toward your semester grade if you implement the rgb26cc() function using high-performance version.
In addition, you need to create a MATLAB script named hw10.m to demonstrate the usage of the rgb62cc () function. In particular, in the script you need to
Read the color image provided (Hanfu_Libra.jpeg) and store pixel values in a variable (imC)
Call rgb26cc() to convert RGB color image stored in imC to corresponding 6-bit color coded image as imG.
Display the original color image and 6-bit color coded image side-by-side in a Figure Window where the original color image is shown on the left and the 6-bit color coded image is shown in the right. (Please notice that when display 6-bit color coded image using imshow() you should see a dark image due to the fact that the intensity range of the 6-bit color code is from 0 to 63. To better visualize a 6-bit color coded image, you can look up the imshow() function in MATLAB help file to specify the display range.)

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.
