  1. 6. Content Based Video Encoding Based on Spatial and TemporalInformation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Theofanis Papakonstantinou; [2023]
    Keywords : ;

    Abstract : A significant amount of video content is produced today that needs to be stored, distributed, andstreamed globally in a cost-effective way. This relies on video compression, a process performedby encoding software that remove spatial redundancy, the similarities within a frame, andtemporal redundancy, the similarities between temporarily adjacent frames.

  3. 7. A hashing algorithm based on a one-way function in the symmetric group Sn

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Adrian Perez Keilty; [2022]
    Keywords : cryptography; hashing; symmetric group; one way function;

    Abstract : We have found an operation between permutations in the symmetric group Sn upon which we have experimentally derived results that can be linked to desirable properties in cryptography, mainly in the domain of one-way functions. From it, we have implemented a beta version of an algorithm for a hashing function by exploiting the operation’s low computational cost for speed and its properties for security. READ MORE

  4. 8. An Analysis of Data Compression Algorithms in the Context of Ultrasonic Bat Bioacoustics

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Max Anderson; Benjamin Anderson; [2022]
    Keywords : bioacoustics; data compression; bats; audio data; ultrasonic;

    Abstract : Audio data compression seeks to reduce the size of sound files, making them easier to store and transfer, and is thus a highly valued tool for those working with large sets of audio data. For example, some biologists work with audio recordings of bats, which are well known for their frequent use of ultrasonic echolocation, and so these biologists can accrue massive amounts of high frequency audio data.

  5. 9. Representation and Efficient Computation of Sparse Matrix for Neural Networks in Customized Hardware

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lihao Yan; [2022]
    Keywords : Convolutional neural networks; Sparse matrix representation; Model compression; Algorithm-hardware co-design; AlexNet; Konvolutionella neurala nätverk; Sparsam matrisrepresentation; Modellkomprimering; Algoritm-hårdvarusamdesign; AlexNet;

    Abstract : Deep Neural Networks are widely applied to various kinds of fields nowadays. However, hundreds of thousands of neurons in each layer result in intensive memory storage requirement and a massive number of operations, making it difficult to employ deep neural networks on mobile devices where the hardware resources are limited.

  6. 10. Swaptions from a Clearinghouse perspective : Hedging swaptions, an option on interest rate swaps, using compression

    University essay from Umeå universitet/Institutionen för fysik

    Author : Joel Forsberg; [2022]
    Keywords : Swaptions; Clearinghouse; Compression; Interest rate swap;

    Abstract : With the increasing popularity of interest rate swaps the need to understandswaptions, an option of an interest rate swap, is of great importance. A swap-tion can be used in both speculative purposes and to hedge against changesin interest rates. The most important thing to understand is the pricing for-mula. READ MORE
