Suppose you are given an image of stellar events which are simply three bright dots or points in different locationsin the spatial domain. Your task is to measure the brightness of each point but unfortunately the imaging systembeing used has an intensity distorting effect that yields a constant multiplicative effect, K, on the image in thespatial domain. That is,faistorted (x, y) = K x original imagea) Provide a simple model for fäzorted(x.y) assuming ideal points each with a given intensity, A1, A2 and Aslocated at (x1.y1), (x2 Y2), and (x3. Y½), respectively.b) Give an enhancement process similar to homomorphic filtering to give you the best chance of accuratelymeasuring the brightness of the points i.e. estimating A1, A2 and As.

Complete these calculations of uncertainty propagation and submit them for the pre-lab assignment. You must show your work in your submission. Your video analysis of the motion of a marble gives it position in frame 23 as (x23. Upa) : (0.134m, mate that you can measure the x and y positions with uncertainty ±0.003 m. The frame rate of the video is 30 frames/s, which means the time interval between frames is At = 0.033 333 s. The uncertainty of the frame rate of a video camera is VERY small. For the sake of this prob- lem, use 8(At) = 1 x 10-6 s. The mass of the marble is (2.031 ± 0.001) × 10-2 kg.

... A centered dataset with n = 116 observations and p = 9 variables was analysed to reduce its dimensionality. The following is a list of singular eigenvalues of X in decreasing order, that is d₁, d2, . . . , dg: 399.1338, 192.1412, 173.0043, 161.6635, 158.0541, 146.6826, 140.0039, 134.1633, 121.1941. A) Compute and write the numerical value of the eigenvalue 4 of Σ. This eigenvalue is located in the position (4, 4) of the matrix A and is simultaneously the sample variance of the score PC4: B) Compute and write the percentage of total variability explained by the Principal component PC4. The number you write should be between 0 and 100 and you should include decimals in your answer. C) A threshold of total variability explained has been set at 80%. How many principal components must you select? Write your answer (integer value).

Please explain the code fully thanks. Using Matlab Write a function g=ImagePad(f,r,c,padtype,loc) with input image f and output image g. If ’padtype’ is ’zeros’, the function should implement zero padding. If ’padtype’ is ’replicate’, replicate padding should be implemented (in which intensity values for pixels outside the boundary are set equal to the intensity value of the nearest boundary pixel). If ’padtype’ is ’mirror’, mirror padding is implemented in which the padded part is a mirror reflection of the image. You should first reflect in the horizontal boundary, then in the veritcal boundary. If ‘loc’ is ’both’, then r rows are added above and r rows are added below the image, and c columns are added to both the left and the right of the image. If ’loc’ is ’post’, then r rows are added below the image, and c columns are added to the right of the image. Test your program and demonstrate that it works.

The figure shown above is a binary images I in which white piİxels have values of one and black pixels have values of zero. First compute derivatives of the image intensities in the x and y directions following the numerical way to obtain Ix and Iy : Ix(i,j)= (I(i+1,j)-I(i-1,j))/2 and Iy(i,j) = (I(i,j+1)-I(i,j-1))/2. For the computation of Ix(i,j) on pixels in the first column Ix(i, j) = I(i+1,j) - I(i,j) or of Iy(i,j) on pixels in the first row Iy(i,j) = I(i,j+1) - I(i,j). For the computation of Ix(i,j) on pixels in the last column Ix(i,j) = I(i,j) - I(i-1,j) or of Iy(i,j) on pixels in the last row Iy(i,j) = I(i,j) - I(i,j-1). Calculate the response R of the Harris corner detector at each pixel based on Ix and ly, assuming (i) a value of k=0.05 in the calculation, (ii) that products of derivatives are summed over an equally weighted 3 by 3 pixel window around each pixel, (iii) that the image is padded with zeros when computing at pixels on the edge. ANSWER: R= (to 2 decimal places)
