Question An image is going to be warped by the transformation f using backward mapping.(i) What is the process of backward mapping as opposed to forward mapping? Which one is generally perferred and why? Are there any circumstances in which the preferred option is impossible?(ii) The warping is performed, however, the result looks 'blocky' - smooth lines have become jagged. Why has this occured? Name a solution that the programmer could implement to improve the quality.

Step 1An image is going to be warped by the transformation f using backward mapping. (i) What is the process of backward mapping as opposed to forward mapping? Which one is generally perferred and why? Are there any circumstances in which the preferred option is impossible? (ii) The warping is performed, however, the result looks 'blocky' - smooth lines have become jagged. Why has this occured? Name a solution that the programmer could implement to improve the quality.Step 2Process of backward mapping as opposed to forward mapping ... Backward MappingThe Backward Design processIdentify desired kesults:- In this phase we decide what thould student know, understand and be able to do? What is worthy of understanding? What enduring undersfanding are desired?\Rightarrow Consider goalsReview Curriculum Expectations\Rightarrow Teacher/students interesto.Determine acceptable evidence \Rightarrow How will we know if student have achieved the derired results and met the Standard? what will we accept as evidence of Student understamoling and proficiency?Consider a raage of assessment methods information contwin like formal and informe assessmets during a unit.\Rightarrow Think the assessors before designing Jpecific units and lessons to defernine how/whether Students hove aftained desired understanding.Plan learving Experiences and Tnstruction:In this phase we decide what activities will equip Student with the needed knowtedge and skille?Packward mapping process: -Select on achievemenf yoal based on learning goals, oufcomes or competencies.Locate the bij idea.Define the assessment that will be evidence of achievement.Decide on formative and Aummative assessments to reach the goal.Last step is identify the instruction strategies and enagement techniques, and resources that Will be used to Auppost the learning actirifies.In forward Mapping, if each Source pixel were evaluated as distinct work item. Forward Mapping penerally preferred fer exampie If you have large source image and Amall destination image, then forward mapping would allow you to bplit the source inage into Segments, then divide them among work Ifemod with segrment data cached in private spaces. A Solution that the programmer could implement to improve the quality..The Solution is to avoid forward mapping and instead use balkwoard mapping Brebward mappinn maps from g\left(x^{\prime}, y^{\prime}\right) to f(x, y). That is, it goes through output inage, g\left(x^{\prime}, y^{\prime}\right), one pixel ad a time and each for position \left(n^{\prime}, y^{\prime}\right) ut uses twe inverse transformation to calculate (n, y)(ii) Jaggies are stair-like lines that appear where there should be "smpoth straight lines. If occur due to the "Stair case effect". This is because line represenfed in vaster mode is approximated by a dequence of pixels. Jaggies can occur for a variefy of reasons, the most common being that the coutput device deesnof have enough resolution to portray a Amooth live.If obtained ocaur when a bit mapped image is converted to a different resolution. In veal-tine compreter graphics especially gaming and anti-aliasivg is used to remove Jaggies created by the edgess  ...
