Abstract Sustainability in our food and fiber agriculture systems is inherently knowledge intensive. It more likely to be achieved by using all the knowledge, technology, resources available, including data-driven agricultural technology precision methods, than relying entirely on human powers of observation, analysis, memory following practical experience. Data collected sensors digested artificial intelligence (AI) can help farmers learn about synergies between domains natural that are key...
Scarcity of freshwater for agriculture has led to increased utilization treated wastewater (TWW), establishing it as a significant and reliable source irrigation water. However, years research indicate that if not managed adequately, TWW may deleteriously affect soil functioning plant productivity, pose hazard human environmental health. This review leverages the experience researchers, stakeholders, policymakers from Israel, United-States, Europe present holistic, multidisciplinary...
Radiometric infrared (IR) imaging is a valuable technique for remote-sensing applications in precision agriculture, such as irrigation monitoring, crop health assessment, and yield estimation. Low-cost uncooled non-radiometric IR cameras offer new implementations agricultural monitoring. However, these have inherent drawbacks that limit their usability, low spatial resolution, spatially variant nonuniformity, lack of radiometric calibration. In this article, we present an end-to-end pipeline...
A hyperspectral (HS) imaging system in the 400–1650 nm range was developed based on a point spectrometer matched to double-wedge prism scanner (Risley prism). This type of is efficient and robust monochromatic laser systems operating under field conditions. Here, we adopted this scanning principle develop an inexpensive replacement for HS camera, suitable application precision agriculture environmental monitoring. However, such challenging, due broadband nature dispersive prisms. The...
Thermal multispectral imagery is imperative for a plethora of environmental applications. Unfortunately, there are no publicly-available datasets thermal multi-spectral images with high spatial resolution that would enable the development algorithms and systems in this field. However, image-to-image (I2I) translation could be used to artificially synthesize such data by transforming largely-available other visual modalities. In most cases, pairs content-wise-aligned input-target not...
Low-cost thermal cameras are inaccurate (usually ±3
IR cameras are widely used for temperature measurements in various applications, including agriculture, medicine, and security. Low-cost have the immense potential to replace expensive radiometric these applications; however, low-cost microbolometer-based prone spatially variant nonuniformity drift measurements, which limit their usability practical scenarios. To address limitations, we propose a novel approach simultaneous estimation correction (NUC) from multiple frames captured by...
The TOMBO system (thin observation module by bound optics) is a multichannel subimaging over single electronic imaging device. Each subsystem provides low-resolution (LR) image from unique lateral point of view. By estimating the image's position, high-resolution (HR) restored series LR images. This paper proposes an multistage algorithm comprised successive stages, improving difficulties in previous suggested schemes. First, registration estimates subchannel shift parameters and eliminates...
A tunable extended depth of field (EDOF) imaging is presented using temporal multiplexing and a low-cost eight-ring, annular liquid crystal spatial light modulator. By changing between different phase profiles in the pupil plane lens we perform several levels EDOF. Using these as "database" it shown by how to decompose
The problem of image restoration space variant blur is common and important. One the most useful descriptions this in its algebraic form I=H*O, where O object represented as a column vector, I vector H PSF matrix that represents optical system. When inverting to restore geometric from blurred known system matrix, limited speed quality by condition. Current design methods focus on quality, therefore if additional processing needed condition taken "as is". In paper we would like present new...
Due to low cost and small size, uncooled microbolometer-based thermal focal plane arrays are very attractive for radiometry. However, being non-cooled, they suffer from temporally spatially dependent changes that require constant calibration. While the gain calibration can be reasonably realized by two-point correction, offset due internal radiation loads poses a complicated scheme. We present new computational optics approach simplifies essential temperature offset. Using two successive...
A growing world population together with a decrease in water resources have resulted deficit sources for agriculture. Nations limited are already using recycled treated as vital source irrigation. In 2019, wastewater made up 45% of the overall agricultural consumption Israel. Since recycling systems work continuously and directly connected to irrigation reservoirs, there is constant risk system malfunctions treatment process. cases fecal origin, this may result pathogens entering water,...
Low cost, weight, and size microbolometer-based thermal focal plane arrays are attractive for thermal-imaging applications. Under environmental loads like those in agricultural remote sensing, these cameras tend to suffer from drift gain offset with time thus require constant calibration. Our goal is skip this step via computational imaging. In a previous work we estimated the unknown value radiometric image of an object, given calibrated gain, pair successive images taken at two different...
A detailed investigation is presented on the tunable extended depth of field (EDOF) method, proposed recently by Klapp et al. [Opt. Lett.39, 1414 (2014)]. This method based temporal multiplexing phase masks, using an annular liquid crystal spatial light modulator possessing a small number rings. Examples 3D simulations used to determine profiles in pupil plane are presented, as well more experimental results. Both and numerical results include comprehensive analysis contrast dependence both...
When motion blur is considered, the optics point spread function (PSF) conventionally assumed to be fixed, and therefore cascading of optical transfer (OTF) with OTF allowed. However, in angular conditions, image distorted by space-variant effects wavefront aberrations, defocus, blur. The proposed model considers these formulates a combined PSF obtained from angle-dependent that acts as weighting function. Results comparison new angular-motion-dependent traditional show significant...
In our previous work we showed the ability to improve optical system's matrix condition by design, thereby improving its robustness noise. It was shown that using singular value decomposition, a target point-spread function (PSF) can be defined for an auxiliary system, which works parallel original system achieve such improvement. this paper, after briefly introducing all optics implementation of show method decompose PSF matrix. This is done through series shifted responses (named...
