Bilinear interpolation is widely used in computer vision for extracting pixel values for positions that lie off the pixel grid in an image. For each sub-pixel, the values of four neighbors are used to compute the interpolated value. This presents a challenge since four pixels must be read from the source image memory for each output pixel. This paper presents an architecture, for implementation within...
This paper presents an embedded platform for image acquisition and processing. It is based on the Texas Instruments' TMS320C6416T, a high performance digital signal processor and Altera's FPGA EP3C25F324, offering 594 Kbits embedded memory, which is enough to design a large FIFO (first in first out) on chip. The digital image data is transferred into FPGA, after pre-processing, it is transferred into...
