  1. 1. The Discrete Wavelet Transform

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Wirén Anton; [2021]
    Keywords : Wavelet theory; multiresolution analysis; image processing.;

    Abstract : In this thesis we will explore the theory behind wavelets. The main focus is on the discrete wavelet transform, although to reach this goal we will also introduce the discrete Fourier transform as it allow us to derive important properties related to wavelet theory, such as the multiresolution analysis.

  2. 2. Automating Geographic Object-Based Image Analysis and Assessing the Methods Transferability : A Case Study Using High Resolution Geografiska SverigedataTM Orthophotos

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Isak Hast; Asmelash Mehari; [2016]
    Keywords : automatic training area selection; scale parameterisation; multiresolution segmentation; classification rule-sets; positional accuracy;

    Abstract : Geographic object-based image analysis (GEOBIA) is an innovative image classification technique that treats spatial features in an image as objects, rather than as pixels; thus resembling closer to that of human perception of the geographic space. However, the process of a GEOBIA application allows for multiple interpretations. READ MORE

  3. 3. Evaluation of pixel based and object based classification methods for land cover mapping with high spatial resolution satellite imagery, in the Amazonas, Brazil

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linnea Jonsson; [2015]

    Abstract : In the state of Acre, Brazil, there is ongoing land use change, where inhabitants of this part of the Amazonian rainforest practice shifting agriculture. Practicing this type of agriculture is, according to the SKY Rainforest Rescue organization, damaging to forest ecosystems. READ MORE

  4. 4. Image Compression by Using Haar Wavelet Transform and Singualr Value Decomposition

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Zunera Idrees; Eliza Hashemiaghjekandi; [2011]
    Keywords : Multi resolution analysis; Haar wavelet transformation MRA ; Average and difference method; Singular value decomposition SVD .;

    Abstract : The rise in digital technology has also rose the use of digital images. The digital imagesrequire much storage space. The compression techniques are used to compress the dataso that it takes up less storage space. In this regard wavelets play important role. READ MORE
