Suppose we want to put the camera in position e(1, 0, 1) and aim it at position a(0, 0, 0) with view up position u(0, 1, 0) in the world coordinate system. Write the related code using the look-at function to setup the model-view matrix.
Consider two images. One should be relatively large, like 512 x 512 pixels that contains several sparsely populated points with magnitude 255, and the other is small such as 15 x 15 that contains a non-symmetric object like, with the object white and the background black for both images. Perform both the correlation, and convolution of the two images separately and correctly label each result. Make the resulting image the same size as the larger input image.
Answer the given question with a proper explanation and step-by-step solution. Each image-processing function that modifies its image argument has the same loop pattern for traversing the image. The only thing that varies is the code used to change each pixel within the loop. Design a single function, named transform, which expects an image and a function as arguments. When this function is called, it should be passed by another function that expects a tuple of integers and returns a tuple of integers. This is the function that transforms the information for an individual pixel (such as converting it to black and white or gray-scale) The transform function contains the loop logic for traversing its image argument. In the body of the loop, the transform function accesses the pixel at the current position, passes it as an argument to the other function, and resets the pixel in the image to the function’s value. Write and test a script that defines this function and uses it to perform at…
In terms of the perspective projection camera model, two things occur simultaneously during a dolly zoom sequence: the camera moves along the z-axis, and the focal distance of the camera changes. The distance moved and the change of focal length are carefully chosen so that the projection of objects at a predefined distance remain at the same image position. Objects at all other distances move relative to one another. A photographer wants to capture two images of a scene captured at either end of a dolly zoom, such that the image positions of points in the world at a distance of α cm relative to the camera that took the first image remain the same. The first image is captured with a focal length of β cm. To capture the second image, the camera was moved γ cm along the z-axis in the negative direction. What focal length should be used to capture the second image to successfully perform the dolly zoom.
Please give me the MATLAB code . Develop a MATLAB function called rotateAboutCenterImage that calculates the 2D transformation matrix that rotates an image about its center (center = width/2, height/2). The function inputs are image width, image height, and rotation angle. The function output is the 2D transformation matrix. Include the numerical results output of the function rotateAboutCenterImage with image width = 320, image height = 240, and rotation angle = π/6 in your report with sufficient precision such that it can be evaluated (hint: use format shortg in MATLAB prior to displaying your results).

While doing Histogram Stretching, we established that we go pixel by pixel through whole image and apply Histogram Stretching Formula for each pixel. So, for example in the following image, if there are 100 pixels, we would do Histogram Stretching Formula 100 times. Do you think we could do Histogram Stretching for whole image and calculate this formula fewer times ? If no why ? If yes, how ?
