A knight at position (r, c) can move in an L-shaped pattern to any of eight positions: moving over one row and up/down two columns to positions (r± 1, c±2), or moving two rows over and one column up/down to positions (r ±2, c ± 1). A rook at position (r, c) can move in a straight line either horizontally or vertically, moving any integral number x of squares. The rook ends up in positions (r±x, c) for a vertical move, or (r, c + x) for a horizontal move. Figure 5.13 A chess board, and the legal moves for a knight (left) or rook (right).

Please summarize the following paragraph below. You can do it in jot notes. the paragraph below are about how you can use fractal techniques for facial recognition the number number if brackets are for the images below ractal theory of iterated contractive transformation has been used in several areas of image processing and computer vision. In this method, similarity between different parts of an image is used for representing of an image by a set of contractive trans- forms on the space of images, for which the fixed point is close to the original image. This concept was first proposed by Barnsley (9) (11) . Jacquin was the first to publish an implementation of fractal image coding in (11) Despite the number of researchers and the proposed methods, several factors can significantly affect face recognition performances, such as the pose, the presence/absence of structural components, facial expressions, occlusion, and illumination variations. Different image compression methods…
(Computer Graphics)Using the Cohen-Sutherland line clipping algorithm, clip the line PQ with coordinates P (-5, 3) and Q (15, 9) against a clipping rectangular window with coordinates (0, 0) and (10, 10) as lower left and upper right corner respectively. Also, find intersection points if any.
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.

example of multimodal text in the form of an image. Then, analyze and discuss its content.
A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”.
