Methodology / Results Planner for FYP-1 Planner for FYP-2 Progress in Part 1 & 2 Q&A Session OVERVIEW : OVERVIEW FYP PART 1: The study of Motion-JPEG2000 video processing/compression is done FYP PART 2: The study of Motion-JPEG2000 video transmission though selected wireless channel is done. INTRODUCTION : INTRODUCTION What is Motion-JPEG2000? Main idea: Video adaptation of the JPEG2000 standard for still photos. Treats a video stream as a series of still photos, compressing each individually. Intra-frame coding: allows for random access and reduce complexity. Ideal for editing due to no inter-frame compression Preserve best image quality after compression for use in high quality video system. Characteristic of Motion-JPEG2000(based by JPEG2000 standard) : Characteristic of Motion-JPEG2000(based by JPEG2000 standard) Includes lossless & lossy mode. - Lossless operation: 5-3 reversible wavelet filter - Lossy operation: 9-7 irreversible wavelet filter Produce compressed data streams with different resolution & quality layers. - smaller resolutions/images with lower quality, not the whole data stream has to be decompressed. Large bit depth of the components. - images with high dynamic range can be preserved after compression & decompression. Low computational complexity rather than video coding standard (MPEG), due to the inter-frame coding. Video structure of intra-frame and inter-frame coding. : Video structure of intra-frame and inter-frame coding. The usage of Motion-JPEG2000 for Digital Cinema camera system (recording & control environment) : h The usage of Motion-JPEG2000 for Digital Cinema camera system (recording & control environment) Slide 8: The block diagram of Motion-JPEG2000 stream scaling multiple output. LITERATURE REVIEW : LITERATURE REVIEW “Motion-JPEG2000 as Part 3 of the JPEG2000 image coding standard is based on the core coding technology of the baseline JPEG2000 Part 1.” Thus, let us see the main idea of the core coding technology of the baseline JPEG2000 Part 1.. JPEG2000 : JPEG2000 Wavelet-based image compression standard. Standard filename extension: - Part 1: *.jp2 (ISO/IEC 15444-1) - Part 2: *.jpx (ISO/IEC 15444-2) - Part 3: *.mj2 (ISO/IEC 15444-3) - Part 4: Compliance - Part 5: Reference software (Java and C) - Part 6: *.jpm (Multi-raster Content) Requires far greater decompression time than JPEG. JPEG2000 features : JPEG2000 features Superior compression performance Multiple resolution representation Progressive transmission Lossy and lossless compression Region of Interest Error resilience Flexible file format Side channel spatial information Pre-Processing steps of JPEG2000 : Pre-Processing steps of JPEG2000 Supports partitioning of the input image - rectangular, non overlapping spatial regions on a regular grid (tiles) Each image can consist of multiple components e.g. RGB - tiling applied to each component separately (in consistent way) Resulting tile components are treated independently in the subsequent coding process. Basic coding algorithm of JPEG2000 : Basic coding algorithm of JPEG2000 3 step transform coder: Discrete Wavelet Transform (DWT) Uniform quantization with central dead-zone Embedded bit-plane coder for the quantized transform coefficient Wavelet Transform : Wavelet Transform JPEG2000 uses 2 different wavelet transforms: Irreversible: 9/7 (tap filter) wavelet transform. Introduces quantization noise that depends on the precision of the decoder Used in lossy coding Wavelet Transform : Wavelet Transform Reversible: 5/3 (tap filter) wavelet transform. Uses only integer coefficient Output does not require rounding No quantization noise Used in lossless coding JPEG2000 standard operation in block diagram : JPEG2000 standard operation in block diagram PROBLEM STATEMENT : PROBLEM STATEMENT Why Motion-JPEG2000 is necessary in video processing field? Primary solution to delivery applications of HD/greater video signal e.g. Digital Cinema standard, Medical and Satellite imagery. PROBLEM STATEMENT : PROBLEM STATEMENT The future parts of JPEG2000 which is continuing to evolve. OBJECTIVES : OBJECTIVES The objectives that is need to achieve throughout the whole project are: Intensive study of MJPEG2000, due to the fact that it is still quite new in the video processing field. Familiarize on the usage of variety software’s that can adapt the processing/compression of MJPEG2000 format. OBJECTIVES : OBJECTIVES Intensive study on the characteristic of the desired video transmitting channel (MC-CDMA & MIMO channel). Video transmitting testing using MC-CDMA channel. Video transmitting testing using MIMO channel. To improve the overall performance evaluation, from video transmitting to video quality. METHODOLOGY & RESULTS : METHODOLOGY & RESULTS METHODOLOGY : METHODOLOGY SUPER© software that is used for compression of RAW video to AVI video format METHODOLOGY : METHODOLOGY LEADTOOLS Multimedia handles the video processing of AVI video to AVI-wrapped MJ2 file. METHODOLOGY : METHODOLOGY DirectShow SDK Filter Graph Editor (GraphEdit), which function as a visual tool for building and testing filter graph. RESULTS : RESULTS SUPER© EVALUATION Compression of RAW video to AVI video format (test video) RESULTS : RESULTS LEADTOOLS Multimedia EVALUATION Compression based on quality of AVI video to AVI-wrapped MJ2 video format. Video, video dimension and video frame rate are based by the previous test video obtained from SUPER© software. RESULTS : RESULTS LEADTOOLS Multimedia EVALUATION RESULTS : RESULTS LEADTOOLS Multimedia EVALUATION PLANNER FYP PART-1 : PLANNER FYP PART-1 PLANNER FYP PART-2 : PLANNER FYP PART-2 PROGRESS IN PART 1 : PROGRESS IN PART 1 Familiarize with the software implementation for the video processing. Improvement video quality base by the MJ2 compression option. PROGRESS IN PART 2 : PROGRESS IN PART 2 Video transmitting testing using MC-CDMA wireless channel. Video transmitting testing using desired MIMO wireless channel. Q & A SESSION : Q & A SESSION THE END : THE END THANK YOU
