Lab Notes 4/24/2013 (WEEK 4 LAB)

This week's topic is still more focused on the filters. The one we used, as in Gaussian Filter, is not appropriate to use in our image prosscessing. As the instructor reconmmened us to take a look at the Matlab's built in filters, we try to use the edge detection to apply the filter after with a conference with TA.

Do list :
1) Do more research about the filters
2) Try every filter that make sense with its definition
3) Apply the most correct filter and do more correction

In researching the filters:
1) sample filtering http://lodev.org/cgtutor/filtering.html
2) useful link for k-means courses.washington.edu/matlab2/Lesson_15.html

Notes for K-means :

Basically, K-means does classify the center of different things.
In a 2-dimensional space( 2D coordinates). As each point point has a specific value, what K-means do is to pick up the value and put them into a cluster. For instance, K has a value of 3, then the function will pick up things and separate them into 3 clusters.

For the process of K- means:
1) pick up the center
2) decide each pixel goes to
3) repeat the process until things stop changing

In order to separate things appropriately, a conclusion came to the surface that we need to figure out an appropriate value for the K.
*There is a built-in k-means command in the Matlab.

Here is the list of problems we faced during the lab:
1) we can not determine which filter to use
2) cannot figure out the value for the filters


Here is the list of good things we had:
1) the "sobel" filter gives us some confidence of figuring out the filter

Filtering and Edge Detection

We researched more about filters and tried to test some of the filter examples we had. Edge Detection should be fine. There is a high chance that we will keep the canny edge detector for our program, the others we have tried were not as detailed as the canny.

Lab Notes 4/17/2013 (WEEK 3 LAB)

This week's topic is  to use the MATLAB to do the Edge Detection and then the Gabor filtering. In short terms, it means to apply the filter to compare the similarity of the two objects, so that the data can be justified in a more correct way.


Here is the list of good things we had :

1.We have the best group numbers!
2. We figured out how to use the 'edge'  command in Matlab.
3. Main W05 is open almost everyday during the week. And there will be software that we need installed.
4. A sample of using the 'imfilter' command in Matlab :
http://www-rohan.sdsu.edu/doc/matlab/toolbox/images/linfilt6.html
5. A sample of using the 'imshow' command in Matlab:             imshow(image1(:,:, 1:3));


Here is the list of problems we faced during the lab:

1. We could not connect our digital storage to the computer. ( So that we had to use our personal computer) Drexel technology is problematic.
2.Matlab crushed at the first time when we tried to let it handle the data.
3.We had problem using the imfilter command at first.
4.We used and understood the 'imshow' in a wrong way.

Lab Notes 4/10/2013 (WEEK 2 LAB)

Today we are performing georeferencing with ArcMap GIS.

First of all, the GIS is totally a new software to all of us, so we basically follow the instruction given by the lecturer.


Here is the one by one step for the instructions in the lab:

1. Remove the "Read only" for the file properties
2. Get the world map from USGS as the base map for our georeferencing.
3. Add our new map to the software and zoom to the area.
4. Set the green box to 128
5. Set 7~8 control points per image as the referencing points
6. Use "turn off the layer" to find the corresponding points for any mistakes and reference.
8. Save the control points
7. Update the georeferencing.
8. create the new image"Rectify". (transformation)
(For self-installing the ArcMap GIS, installing the service pack #5 is primary requested).


Here is the list of problems we faced during the lab:

1. We could not add the image into the GIS.
2. It was hard to choose control points
3. There are some houses gone in the new map, so that we cannot even reference to a point

Project Design Proposal

Freshman Engineering Design Lab

“Satellite Image Processing”

Project Design Proposal

Date Submitted: April 10, 2013

Submitted to:	Anu Pradhan, arp69@drexel.edu James Worcester, james.worcester2@gmail.com
Group Members:	Dongen Zhou, dz78@drexel.edu
	Eddie Tang, et354@drexel.edu

Abstract:

1        Introduction

Discuss the motivation and goals of the planned project. Discuss the learning objectives, major tasks, technical challenges, and desired outcomes.

2        Deliverables

Describe in detail what you will produce at the conclusion of the project: examples include physical prototypes, computer models, simulation results, algorithms and programs, design studies, lab test results.

3        Technical Activities

Elaborate on the major tasks of the project and how these tasks will allow you to address the technical challenges of the project.

3.1      Georeferencing

“ In simple terms, georeferencing just means relating information to geographic location.”[1] Specifically in processing satellite images, georeferencing is being used to locate objects in the terms of geographical projections, or coordinating systems. Since it is a process of creating a whole system, an automatic georeferencing procedure can be done as: “ 1. Scanning a paper topographic plan (map board) and obtaining a digital raster image; 2. Referencing control points (using a coordinate grid) and transformation; 3. Vectorization.”[2]

3.2      Sample Subsection 2

This is an example of a subsection. To get the required formatting, use the Microsoft word “Heading 2” style. The paragraph text here uses the “Normal” style.

4        Project Timeline

During spring term, you will have approximately 10 weeks to complete your project. Provide a project timeline (a Gannt chart) that shows the major tasks and their duration. If this project requires you to learn a specific skill, time should be allocated for this in your timeline. The following table is for illustration only and the specific tasks listed will likely not apply.

	Week
Task	1	2	3	4	5	6	7	8	9	10
Literature study	x	x
Mechanical design		x	x	x	x	x
Electrical design			x	x	x	x	x
System integration						x	x	x
Testing							x	x	x
Final report preparation								x	x	x

5        Facilities and Resources

Describe any resources you are expected to use during the course of the project. This includes anything that is necessary for the completion of the project and that your group does not already possess. Examples include use of machine shop tools, rapid prototyping machine, faculty research space and equipment, on or off-campus work space. If no resources are needed, state this.

6        Expertise

Some projects may require group members to have skills in certain areas prior to starting the project while other projects may require group members to acquire these skills through the course of the project. Describe any specialized skills that may be needed for this project. Some examples include

• Familiarity with a specific software package
• Computer programming experience
• Knowledge of basic circuit theory
• Use of machine tools

7        Budget (if appropriate)

For any projects that require the purchase of materials, either by the group or their advisor, a budget must be provided. This should be organized by category, and for each expense category there should be a brief description of the expense. For example, see the following subsections.

Category	Projected Cost
Mechanical Hardware	$23.45
Stepper Motors	$57.01
Motor Controller	$110.12
TOTAL	$190.58
