“…GrabCut algorithm basically adopts the segmentation framework of graph cuts, but improves the judgment model of foreground and background attribution possibility, parameter estimation method, and interaction mode in the framework [13]. Figure 1 is a schematic diagram of the segmentation framework of GrabCut.…”

This study aimed to further enhance and enrich users’ visual experience, provide users with a more infectious image sense, and further promote the development of multidimensional, virtualized, and interactive graphic advertising design applications. This study presents a design idea of print advertisement based on computer image interactive virtual technology. Based on the in-depth analysis of the multidimensional expression of plane image interactive virtualization, this idea carries out interactive virtual design with the help of interactive virtual image segmentation algorithm and plane advertising image element optimization technology. Through the test of image interactive edge extraction function on MATLAB platform, the simulation results show that the edge width of single side extraction results with different gray levels of the same width and different widths of the same gray level are 9 pixels, the gray values are 5a0, 110, and 200, respectively, and the edge width corresponds to 3, 9, and 15 pixels, respectively. The results show that the system can effectively enhance the image definition and obtain better print advertising design effect.

“…For instance, Mathews and Wikle (2019) comprehensively explored the pedagogies for higher GIS education, for example, web-based learning. Some other exemplary studies include those related to the history of GIS education (Unwin et al, 2011), the role of GIS within higher education (Sinton, 2009), blended GIS learning strategy (Ooms et al, 2015), core competences for GIS learning (Schulze et al, 2013), interdisciplinary collaboration in GIS education (Kawabata et al, 2010), continuing education and certificate programs (Wikle, 1998), GIS learning and spatial thinking (Lee & Bednarz, 2009), critical GIS pedagogies (Elwood & Wilson, 2017), CyberGIS pedagogy (Ricker & Thatcher, 2017), WebGIS courses (Goldberg et al, 2021), model of GIS education based on inquiry-based learning (Jakab et al, 2017), and GIS learning with Communities of Practice (Tate & Jarvis, 2017).…”

This study investigated GIS students' perspectives on emergency online learning (EOL) during the Covid-19 pandemic through a case study at National University of Singapore.Questionnaire surveys administered to three GIS courses were conducted, the result of which suggests that the GIS teaching could be completed effectively online during the crisis. In addition, the positive and negative influences of this learning mode have been discussed in connection to relevant student perspectives on social media and relevant findings in the literature. Relatively, senior and independent learners adapted better to the EOL, while beginners and less self-disciplined learners may need more face-to-face guidance, interactions, and direct supervision. It is worth pointing out that despite some students seeing the demand for a higher level of self-discipline as being negative, others saw this property contributed to them being better independent learners with self-motivation, suggesting the need for a nuanced interpretation of the results that consider perspectives. Based on the pros and cons of the EOL investigated, this article further stresses the need to cultivate a post-pandemic blended GIS learning pedagogy for enhancing higher GIS education's quality and resilience in times of crisis.
