For a given target point, the acquisition time t is related to the azimuth coordinate (lin) of the SAR image through: t t0 ’tŸ lin 1 (4) where ' t is related to the pixel size in azimuth direction. Digital Image Processing Multiple choice Questions unit wise UNIT-1 : INTRODUCTION TO DIGITAL IMAGE PROCESSING 1. , when x and y are both integers Image interpolation refers to the “guess” of intensity values at missing locations, i. The geometric transformation of digital images is an important tool for modifying the spatial relationships between pixels in an image, and has become an essential element for the post-processing of digital images. 2 in your textbook Logarithmic Transformations can be used to brighten the intensities of an image (like the Gamma Transformation, where gamma 1). However, some adaptations to the learning materials and the teaching approaches have to be made so that the learning needs of visually impaired children can be met. The systems that allow us to experience the auditory world in three spatial dimensions are extraordinarily complex. Some transform techniques are: Fourier Transform (FFT, DFT, WFT) Discrete Cosine Transform (DCT) Walsh-Hadamand Transform (WHT) Wavelet Transform (CWT, DWT, FWT). You could think of a geometric point transformation as just moving a point from one location to another, like this: But that terminology quickly gets a little confusing.
