Chocolate lover: July 2011
http://jrvitug.blogspot.com/2011_07_01_archive.html
Wednesday, July 13, 2011. Even if everybody thinks you're not. I still believe that you are". We are human beings. not perfect. but we shouldn't be deprived of the chance to improve ourselves and show the society the better side of us. Just some random thoughts from a very lazy evening. I remember the time when I last spoke about this. Subscribe to: Posts (Atom).

CINDY 186: Activity 18 | Noise Models and Basic Image Restoration
http://ccesporlas-ap186.blogspot.com/2009/10/activity-18-noise-models-and-basic.html
Monday, October 5, 2009. Activity 18 Noise Models and Basic Image Restoration. Image restoration is a basic image processing application where an image that has been degraded or damaged is being recovered. To recover the image, the degradation must be known and thus can be used in restoring the image. Figure 1. PDFs of different noise types. Figure 2. Types of filtering used. Figure 3. Test image and its PDF. Figure 4 shows the noisy image for the added Gaussian noise with mean = 0.5 and standard dev...

CINDY 186: Activity 17 | Photometric Stereo
http://ccesporlas-ap186.blogspot.com/2009/09/activity-17-photometric-stereo.html
Wednesday, September 9, 2009. Activity 17 Photometric Stereo. Figure 1. Photometric Stereo. Equation 1. Intensity at point P(x,y). In this activity, we use four images of an object taken with different light source positions and use it to reconstruct the 3D structure of the illuminated area, as shown by Figure 2. Figure 2. Images of object at different light source positions. To calculate for the surface normal of the object we need to get the far away point source locations given by V. Buno, Luis III.

On pics, physics, and more! Sunday, October 3, 2010. Lessons from drinking sessions.part 1. Nakausap ko si Fidel Rillo habang ako ay nakipag-inuman sa bahay ng aming kaibigan (tawagin natin Mambo) bilang despidida nya papuntang Germany. Nais kong ibahagi ang mga bagay na napagusapan namin. Tinanong ako ng "What is God? Isang sagot ang binigay sa akin ng tatay ng aking kaibigan. "it is the search for truth". It is the search for truth.science and God. Subscribe to: Post Comments (Atom).

Chocolate lover: Activity 18 Noise model and basic image restoration
http://jrvitug.blogspot.com/2009/10/activity-18-noise-model-and-basic-image.html
Saturday, October 10, 2009. Activity 18 Noise model and basic image restoration. In this activity, we try to demonstrate the different types of noise and image restoration techniques. Similar to image enhancement technique, this method aims to improve the quality of images surrounded with noise. However, this technique is more of object type as compared to image enhancement technique which is subjective in nature. Figure 1. Clean image and its PDF. Where z is the gray level value,. Is the average, and.

On pics, physics, and more! Thursday, August 6, 2009. Activity 12: Color Image Segmentation. Segmentation by thresholding will not always work especially when the area of interest has the same grayscale value as the background. In such cases, segmentation can be done using the color of the image of interest. In this activity, we're going to demonstrate parametric and non-parametric color segmentation. Normalize Chromaticity Coordinates (NCC). Can be obtained from r. Essentially, what this PDF does is to ...

Thursday, July 23, 2009. Enhancement in the Frequency Domain. Image enhancement is any digital process which aims to improve the quality of images by adjusting the contrast, brightness, sharpness, boundaries and edges [1]. One of the techniques used to enhance the visual qualities of images is by filtering out unwanted frequencies. This is done through the use of a mask. A mask is a small square window of values by which the current pixel and its neighbor are weighted to produce and output pixel [1].

On pics, physics, and more! Thursday, July 23, 2009. Activity 8: Morphological Operations. In this activity, we're going to demonstrate two basic morphological operations, dilation and erosion. We proceed by defining dilation and erosion using set theory and provide examples using different images. To futher understand dilation and erosion better, the reader is recommended to predict the outcome of dilation and erosion on a piece of paper before programming it on a computer. From our activity manual, "Th...
