what is this image

Question: Comment on the resolution of the image. informations 1) pixel dimensions of the image = 2967x4963 2)total pixel=14725221 2)maximum and minimum grey level of the image= 243 and 7 4) you can see the matlab image below

Pick a region of interest in the image making sure there is a CORNER in that region. Pick a 5 x 5 image patch in that region that constitutes the corner. Perform the steps of HARRIS CORNER DETECTION manually and note the pixels that correspond to the CORNER.   make code in python

Given the 3x3 color image with red, green, and blue pixel values: [90 100 1101 R = 90 100 100 , G = 90 100 110 , B = 80 90 110 190 100 90. [100 110 120] [110 100 110] 80 100 100] 90 100 110] a) Calculate the region covariance matrix of the above image. b) Can you compare the above image with a 2x2 image region: [100 1001 R [90 1001 190 100] [110 105] B = 90 100 G 80 95 using the region covariance approach? Explain your answer.

In image touching, explain how color tones can be corrected in an image using the curve adjustment layer or palette in adobe photoshop

We begin with resizing the image. Resizing images is something you will want to do frequently when working in multimedia. Click on Image | Resize and set the dimensions to 640 x 480 (be very careful to set the image to 640 x 480 pixels, not 640 x 480 percent of its original size, or you will create an extremely large image!).  Why would you use Resize and not Canvas Size?

How much storage space is required for a single image?

RGB to gray:  Take an image from your system and plot both original image and grayscale image of same image in MATLAB. Provide Matlab code and attach both original and grayscale image.

Anti-Aliasing Explain how subpixel rendering works and how this process can reduce aliasing effects.

What is the minimum amount of storage space required for a single image?

CMYK is better for blown-up pictures than RGB.

Consider a bitmap image and elaborate the color depth for it?

Question 4 In Image retouching, explain how colour tones can be corrected in an image using the curve adjustment layer or palette in Adobe Photoshop

answer quickly

Choose one of the following tools in the program GIMP: desaturate, clone, rotate, increase contrast, or invert and explain what it does to the pixels of the image.

How much capacity is needed to store a single image?

Compare and contrast the benefits and drawbacks of the different image representations. If you only had a limited amount of computer resources, which format would you choose?

Computer Science Question

Q1: Rescale the following image to be 50% smaller than its original size (you should avoid Aliasing) 25 19 17 19 22 23 19 20 22 32 32 33 20 44 43 46 Q2: Rescale the following image to be 200% bigger than its original size using both Nearest neighbor interpolation BİLinear interpolation 25 17 19 19 22 32

Compared to an RGB color value of 50, the RGB color value of 150 would be...    brighter. darker. less saturated. more saturated.

When rendering a triangle mesh in a pixel shader, which of the following quantities is not a property of the material applied to the surface? O The specular reflection color O The albedo p O The color of the light source O The diffuse reflection color O The specular power
